Well, that depends a bit on what is meant by "flood" in that context.

If you mean an event that resulted in the inundation of the land surface, to sufficient depth to cover at least the higher foothills of mountains, for several weeks by act of divine intervention such that there is no evidence of such an event in the geological record (or, for example, the genetic record of living species) then, of course, such an event can't be disproven. The lack of evidence for such an event is part of the event.

On the other hand, if you have the same inundation event but want to claim that there was no special action by God to cover up the evidence then there's no real option but to declare it disproven. There's no way that such an event could happen without leaving evidence.

OK, Take sea created fossils on high mountains. Now, that is evidence..of what, is the question. You can say water was up there, or you can say the land pushed up over a few mill years. Now the theory you apply is the critical issue in interpreting the evidence. You can say it was flood or inverted faulting, volcanism, earthguakes etc. It may be both or all. What you musn't deny is that the way you look at evidence is dictated by your theoretical preconceptions.
Evolution is a theory of origins. It cannot be proven or otherwise. You choose to believe it and you explain evidence in other ways than a flood.I don't. Am I an ostrich? MT would think so. Is he influenced by his world view? I think so.

And MT. The Bible says a flood happened. My interpretation of the Scripture is irrelevant. It categorically states it.

You don't believe what the Bible plainly says everywhere. Nobody does, because it contradicts itself. But it doesn't, you say. Only because you don't take both of the contradictory things actually literally.

Well, if you accept the basic physics of nuclear processes and radioactive decay then we know that those fossils were created millions of years ago, and that different fossil beds were created at different times over the course of hundreds of millions of years. Of course, known tectonic processes are more than capable of pushing mountains up, taking fossils with them. There's no real problem there, unless for some perverse reason you wish to reject practically the whole of the scientific enterprise.

On the other hand, as evidence of a global flood fossilised marine creatures on a mountain top are pretty poor evidence. Proponents of such a conjecture need to explain why the fossils are from a single ecosystem. Why aren't there fossils from other marine ecosystems, or adjacent terrestrial environments. Either you have a Flood with the characteristics of floods we know (just bigger), which are turbulent and violent with stuff from all sorts of places jumbled together. Or, you have an incredibly placid Flood unlike anything in history that allows ecosystems to be preserved largely intact in-situ. And, in the second case we're back in the realm of God doing it in such a manner that it doesn't appear to have happened at all, with God causing the Flood in such an un-floodlike manner that the evidence looks like it was left by a completely different process.

Seriously? Quite a category difference here. Don't you think you are kind of ignoring context?

But you are quite right. I do not believe what the Bible says is everywhere to be literally applied, or that its every injunction is for today; or that every word is to be literalistically interpreted. Why ever did you think that? I do not, however, think God would mislead us in the historicity of the flood narrative.

Bearing in mind I'm no scientist, some creationist aguments query whether C 14 would have been produced in the biological system prior to the flood because they postulate that a vapour canopy would have shielded it from cosmic rays. This of course would give pre flood fossils the impression of infinite age when dated by this method.

Now, my point is not to argue the toss about this but just to point out that the argument comes down to dating and that not everyone accepts the dating process based on radio active decay.

That may well be the case. Most people nevertheless view it that way. Whether that is their ignorance or the fact that it has reinvented itself is a moot point.

Some of the usual well-known chronological/archaeological frauds have been put forward, but they turn out just window dressing. Their dodgy books and claims are not the real reason for the literal belief in the flood that's being held - which probably ultimately derives from Christology.

The sad thing is that the association of belief in the credibility of Jesus with well-known and easily disproved frauds can actually end up putting Jesus in that category for a lot of people. Instead of elevating the Bible, this approach actually ends up dragging it down to the level of the 'God was a Spaceman' 'Secrets of Atlantis' 'Holy Blood and Holy Grail' type books to be found in the New Age/Alternative history remainder bin.

L.

Humble is not uncritical acceptance of anything; it is normally an acknowledgement one doesn't know everything and the holding of positions lightly IMV. I was merely pointing out it is a rare commodity rather than claiming to have it.

Regarding the real reason for belief in a literal flood. You are right I think to say it comes down to Christ but everything does really.

Interestingly, the accusations that creationists are ostriches could also be levelled at the other side. The vested interest in evolutionary theory and chance based origins allows us to invent our oun morality and cut ourselves loose from values that contadict our will to live how we want and act as we want. My primary objection to evolution is moral not scientific. Survival of the fittest makes for rubbish ethics IMV.

OK, I'll try and explain in a way accessible to a non-scientist. We'll start with 14C dating, as you raised it, even though it's irrelevant to dating fossils. 14C is mostly* produced by reactions with cosmic radiation in the upper atmosphere. Atmospheric circulation then brings it down to the surface where it is absorbed by plants, and then animals as they eat the plants. For a 'vapour canopy' to prevent 14C production it would need to exist above the atmosphere, which would be physically impossible, and to be so dense that it would significantly restrict sunlight reaching the surface. Such a canopy would certainly obscure the stars and moon far more effectively than a cloudy night. Perhaps it's your idea of Paradise, but I can't imagine Eden being a perpetual twilight of heavily filtered diffuse sunlight and very little warmth.

The half life of 14C, about 5730y, makes it an ideal method of dating modern stuff less than about 50000 years old (it's a bit of a problem for really modern stuff from the last few centuries because human activity has dumped low 14C carbon into the atmosphere by burning fossil fuels and then added a load of additional 14C from nuclear power and bombs).

There are a whole load of additional dating methods that cover different time scales that are largely independent of cosmic rays. Dating methods based on the decay of primodial radioactive materials (ie: stuff that was incorporated into the earth when the planet formed) can stretch dating back billions of years - that's basically using the uranium series, thorium series and 40K decays. It's these methods that are used to date fossil beds.

Luminescence methods, which use electrons trapped in excited states in quartz or feldspar crystals, can date materials upto a few hundred thousand years old. They're no good for dating fossils, but can provide an independent cross-check on 14C dates and extend chronologies back from them. Events that leave annual or seasonal records can also produce dating evidence. This would include tree-rings with one ring each year (and variations on ring size depending on the environmental conditions each year) which with trees giving overlapping dates can take us back in time a few millenia. Similar patterns in glaciers (reflecting seasonal influxes of fresh snow) or lake sediments can do the same. Again, no good for dating fossils but further independent verification of 14C dates (actually, generally they can provide absolute dates as counting rings/layers gives a precise age, and so are often used as a calibration on 14C to adjust for changes in cosmic ray flux and anthropogenic influences).

quote:
Now, my point is not to argue the toss about this but just to point out that the argument comes down to dating and that not everyone accepts the dating process based on radio active decay.
It's clearly the case that not everyone accepts dating methods based on radioactive decay. But, to reject that dating method you need to reject a large chunk of nuclear and quantum physics. And, usually that goes hand in hand with rejecting the scientific disciplines of geology (which had determined that the earth is old long before there was an absolute method of dating the past), and biology (because, again, the evidence of biology for evolution over long periods is consistent with the dating methods). And, because the fields of biology, geology and physics are basically outworkings of the scientific method, presumably they think there's something deeply flawed about the scientific method as it's failed to 'correct' the findings of these fields of investigation.

As I said, some people perversely reject practically the whole of the scientific enterprise.


-----------
* Most 14C is formed in the atmosphere, a very small proportion is formed at the surface. This doesn't affect the argument against a 'vapour canopy' because it's such a small contribution to the total. It can be an important contribution to some dating methods though. In particular surface-exposure dating which uses cosmogenic isotopes, including 14C, formed in exposed rock surfaces by the action of the very small fraction of cosmic rays that reach the surface.

It is the category of narrative. The story actually makes historical claims. Not every story in scripture does that.

No. You interpret the passage as narrative. And, it's your interpretation that it makes historical claims. Which is not the same as it actually being narrative with historical claims.

I've not generally got a problem with carbon-dating, but when I read this I feel like there's a step missing. If there's been a dump of 14C in the last few centuries, why would that only be a problem for dating modern things?

Can you clarify, please? I take it that one reason is that ancient things aren't incorporating any further atmospheric carbon. However, I would have thought that there'd also be a problem in assuming what the base value for 14C was, if we've been altering it since before we actually had the know-how to calculate it.

So you assert. To say a text that clearly says something doesn't say it is actually to deny the possibility of objective communication through language. It's not honest.

If you want to see the flood story as allegory I think the onus is on you to make the case. You'd have to show somehow that authorial intent was in that direction, that the historical context implied allegory, that the story's internal consistency demanded such a reading and that other Biblical writer's viewed it in this light.

If you have done those things to your own satisfaction then I would grant that you are honest, if wrong, IMV. If you have not made such a case to your own satisfaction, you are in denial about the Bible's authority because it confronts your personal belief system or lifestyle agenda. Romans 1:21,22 covers the case,"..their foolish heart was darkened,professing themselves to be wise they became fools."

We've been over this in the other thread.

Genesis 7:11b: on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened.
You say there is no indication in the text to justify treating this as allegory. It's really what happened.
You say there is no indication in the text to justify treating this as metaphor. There really are windows in the heavens. Oh wait - you don't say that.
You know that sciences says that there aren't literal windows in the sky so here you say that the Bible isn't being literal. But you don't make the case that it's a metaphor from the text: you just handwave it.

If you don't need to make the case that there's no windows from the text - if it's just nitpicking to ask you to - then you don't need to make the case that the whole flood story is an allegory from the text. It's just nitpicking to say that it has to be actual history.

Well, whatever. What I object to is being told I'm 'interpreting'as if this was some self evident rebuttal of a 'plain text' reading of the story, and posing the question, 'if that is the case, how we can 'know' anything through the medium of language?

I think I am bowing out now.

I see the flood story as history but viewed through ancient eyes - i.e. the whole known world was flooded and the rest of the story grew from there.

I've given lots of reasons for thinking so (the main one being the impossibility of life without pollinating insects - which no-one has answered) and would be repeating myself if I stay in the discussion.

However, I would have thought that there'd also be a problem in assuming what the base value for 14C was, if we've been altering it since before we actually had the know-how to calculate it.

Plants take up carbon through photosynthesis, converting atmospheric CO2 to sugars and other long-chain carbon molecules, in proportion to the isotopic abundances of 12C, 13C and 14C at the time. When a plant dies, that exchange of carbon stops, and the carbon in the plant becomes fixed until the plant decays (or, is eaten). Even decayed plant matter (eg: peat) doesn't significantly exchange carbon with the atmosphere in a manner that would alter the isotopic composition. A sample of wood from a tree that died 1000y ago would have the carbon-isotope ratio of the atmosphere 1000y ago, less the 14C that has decayed. A sample of wood from a tree that died 10y ago would have the carbon-isotope ratio of the atmosphere 10y ago. The complication with modern samples is that the significant swings in atmospheric carbon isotope concentrations create concentration ratios in the samples that are consistent with older (or, newer) samples as well. There are natural variations in atmospheric concentrations, following changes in cosmic ray flux, which also create problematic results (as an extreme example, if the production rate over a 100y period slowed at a rate equivalent to the decay rate of 14C then samples from plants that died throughout that century would have the same carbon isotope ratio and the same apparent age). Which is why we use a calibration curve, and produce results that show the probability of different ages based on the observed isotope ratio. Often you'd need other data to determine which age is most likely to be true (eg: if your sample was from a building that was known to exist in 1800 and one of your possible dates is 1850 you can reasonably exclude that one).

If you want to see the flood story as allegory I think the onus is on you to make the case.

First off, we all interpret the Bible. The decision that a "plain reading" is possible is, in itself, an act of interpretation. When you start deciding that some passages are best understood with a "plain reading" and others need more nuanced study, you're interpreting. Most of us read the Bible in translation; translation is an act of interpretation. There's absolutely nothing wrong with interpreting Scripture. Indeed, to fail to do so would be IMO a means of not listening to what it says and deny it's authority to address issues of our lives today. The problem comes when one interpretation is arbitarily held as superior to another.

To address the main point. Evidence that the Flood narrative is not best understood as a description of objective, historical events. There's so many potential points I could make, even if I don't mention the fact that science tells us it can't possibly be.

  1. There's no evidence that the ancient world had an understanding of historical narrative that we would recognise as imparting objective accounts of what actually happened. Ancient histories are almost always highly selective in their choice of what parts of a story to include, they're almost always written with a specific aim. In many apsects they read more like propoganda than anything else.
  2. The Flood narrative sits within a section of the Bible that includes many other stories that include fantastical elements - talking snakes, magical trees, angels with flaming swords, people of incredible age, towers that reach to the heavens etc. It seems inappropriate to take one story from that collection of fantasies and declare it to be actual history.
  3. The story itself includes impossible elements. The Ark was big, but not that big ... even with a small number of animals from different species it wouldn't be big enough for representatives of all species, let alone the food they'd need. Plus the issues of getting those animals to the Ark. The story doesn't tell us anything about how fish and plants survived the Flood, yet we have an olive tree flourishing almost as soon as dry land reappears.
That's just for starters without even really thinking about it.

I'm told that Herodotus is considered the first example of a modern historical narrative.

However, it seems to me that it isn't an absolute water-shed. For instance, the books of Kings and Samuel seem closer to history than the start of Genesis. And from Abraham onwards in Genesis seems to be somewhere between the two.

And if you've read Herodotus, you'd know what a credulous old gossip he was. He was the News of the World (or other ridiculous tabloid) for his time, innocently writing down whatever anyone told him, without inquiring whether his interlocutor was drunk or making shit up. About as trustworthy as News of the World too; the odd fact may slip in, but it never gets in the way of a good story.

Neither Herodotus nor any of the early Greek or Roman historians wrote objective history by modern standards. Broadly, they got the big events right, but just about everything else was up fro grabs. The defeat of Loeonidas happened, for example -- but only the fact that the Spartan force lost to the Persians is certainly true. Nothing else in the accounts is -- it may be, but no one can say for sure. The battle of Marathon happened, and the Greeks won -- but everything else in the story is up for grabs. And that's the general pattern.

More specifically, it is as certain as anything can be that no speech recorded as having been given by any speaker was actually delivered like that. I suppose one could argue that Caesar's speeches in the Gallic Wars are possible -- he gave the speeches and may have had his notes to hand when writing the book -- but he is just as likely to have remembered the general sense of what he ought to have said and written that down. One might also make an exception for the famous speech by Pericles, on the basis that its fame was instant and it may have been written down at the time.

For modern ideas of objective history you have to look to the Renaissance at the earliest. And remember that even 18th century historians (Macaulay, for example) had huge biases that are reflected in how they wrote and what they said happened.

So you assert. To say a text that clearly says something doesn't say it is actually to deny the possibility of objective communication through language. It's not honest.

If you want to see the flood story as allegory I think the onus is on you to make the case.

First off, we all interpret the Bible. The decision that a "plain reading" is possible is, in itself, an act of interpretation. When you start deciding that some passages are best understood with a "plain reading" and others need more nuanced study, you're interpreting.

So,to summarise your view, "Because it is supernatural, it didn't happen." Fair comment? Thats an old chestnut really.

Regarding historicity claims, I suppose you could count the times the phrase "These are the generations of.." is used in Gen 1-11. Six times in fact. Clearly authorial intent was to reflect a narrative history. Elesewhere in scripture, The flood is mentioned by Job, the Pslams, Matthew, Peter, maybe otherss. In pretty well all cases (Psalms is poetry genre,) the references suggest those writers thought it was factual not allegorical.

By the way, using a conservative cubit length of 18inches, The ark was 450 feet long and contained 1.5 million cubic feet of storage over its three decks.

Nothing is clear about interpreting scripture. You think the repetition of that formula favours seeing the passage as history. I think it rather tells in the opposite direction. Formulaic structures are more often used in myth than history. "Once upon a time" doesn't start a history, it starts a fairy tale. Literally it says "this really happened". But it is not used literally. And whether or not things are meant literally is exactly the thing we are arguing, so it is a good example of how appearances can be deceiving.

That could very well be. I don't know the passages --and whatever other things I'd need to know to properly exegete them-- well enough to say one way or the other. But if so, maybe they were just wrong. Is nobody wrong in the Bible? The writer of Joshua (I think it is) wrote that the sun stood still in the sky. He was wrong. Oh well. That doesn't impinge on my faith at all.

Ah, the argument by big numbers. 1.5 million square feet sounds like a lot, but what do the Ark dimensions translate to in modern terms?

If we assume a roughly rectangular footprint (no point in making the Ark capable of navigation since there was nowhere to go) each deck (300 cubits by 50 cubits, or 450 feet by 75 feet using Jamat's eighteen inch cubit) would have a gross footprint of 33,750 square feet and the three decks would have a combined footprint of 101,250 square feet. Of course some of this area would have to be taken up with the Ark's structural members as well as hatches and ladders to move between decks, but it at least gives us a rough idea of the size. By way of modern comparison the playing area of an American football field (including end zones) is 57,600 square feet, giving the Ark a combined footprint equal to about 1.75 American football fields. For those who prefer a more international system, a football/soccer pitch has an area between 69,300 square feet and 86,400 square feet, meaning the Ark would be somewhere between 1.2 and 1.45 football fields for anywhere outside the United States. That's not a lot of room for specimens of all the world's animal life plus the necessary fodder to keep them alive for half a year.

No, that doesn't seem to be entirely fair comment. I have no problems with events happening by divine action - I don't, for example,
claim the Resurrection didn't happen because it was a supernatural event.

My comments were aimed at showing that within the Flood story, and stories that set the context for it, there are elements that indicate quite strongly that there was no intention of it being read as a factual account of historical events. It is within attempt to address the points I raised that the supernatural tends to be invoked ... maybe Noah didn't need to store food because the animals were fed by God, perhaps with some form of manna (which the storyteller decided was a sufficiently trivial point that he omitted to tell us).

And far more,that indicate the opposite.

BTW, since God can incarnate himself in human form, die in that body and resurrect himself thus displaying his amazing nature of love and incredible power, why can't you credit that he did the things he said he did in Gen 1-11, for the reasons he said he did them?

Myth is, of course, a human cultural memory primarily. God's actions are the foundation of all human myth so whats the deal that his Bible contains what seems to us, mythical elements?

Croesos: Ah, the argument by big numbers. 1.5 million square feet sounds like a lot, but what do the Ark dimensions translate to in modern terms?
The cubit could have been up to 24 inches.

Volume is more the issue than square feet though.

In 1892 one Charles A Totten was a Yale Professor of Military science and tactics and he wrote a treatise on the Ark's size. He thought a cubit was 24 inches based on Eze 43:13.

This would give a vessel 600 feet by 100 feet by 60 feet. It would equate in volume to 10,000 railway box cars.

Noah was allowed 120 years to build it and remember the Bible 'species' was probably animals cabable of interbreeding. Dogs, wolves,jackels and dingoes, for instance, could have been represented by one pair.

Apparently given the ships dimensions, the issue becomes Noah's capability of building such a vessel rather than whether it was big enough for the purpose.

Mildly intrigued to find out whether Noah (and assorted others) were actually human. Lifespans long enough to allow for 120 years of ark-building make it look like Noah wasn't "ONE OF US" in the first place

Or is it possible that the writers were exaggerating just the leats little bit, maybe to prove that THEIR guy was in some way better than some other tribe's Guy? (which was almost certainly the origin of Methuselah's extreme old age)

So, you think that the estimated 5 million species on the planet could fit in there, and somehow find their habitats once they got out? Species so fine-tuned to their niches that one is a mite that lives on the feet of an ant that lives on an epiphyte of a vine of a tree in a certain cloud forest on a specific mountain in Chile?

Get real. There is *no* scenario where the ark or flood is reasonable. Your "humility" in this thread involves a lot of arrogance in dismissing 97 different areas of science which say there is no way this happened. None. whatsoever.

Perhaps that is because 'Science' is actually the work of fallible,fallen humans with an agenda to support rather than some kind of secular 'papal' authority; and why this is a bona fide 'dead horse'.

OK, I'll try and explain in a way accessible to a non-scientist. We'll start with 14C dating, as you raised it, even though it's irrelevant to dating fossils. 14C is mostly* produced by reactions with cosmic radiation in the upper atmosphere. Atmospheric circulation then brings it down to the surface where it is absorbed by plants, and then animals as they eat the plants. For a 'vapour canopy' to prevent 14C production it would need to exist above the atmosphere, which would be physically impossible, and to be so dense that it would significantly restrict sunlight reaching the surface. Such a canopy would certainly obscure the stars and moon far more effectively than a cloudy night. Perhaps it's your idea of Paradise, but I can't imagine Eden being a perpetual twilight of heavily filtered diffuse sunlight and very little warmth.

The half life of 14C, about 5730y, makes it an ideal method of dating modern stuff less than about 50000 years old (it's a bit of a problem for really modern stuff from the last few centuries because human activity has dumped low 14C carbon into the atmosphere by burning fossil fuels and then added a load of additional 14C from nuclear power and bombs).

There are a whole load of additional dating methods that cover different time scales that are largely independent of cosmic rays. Dating methods based on the decay of primodial radioactive materials (ie: stuff that was incorporated into the earth when the planet formed) can stretch dating back billions of years - that's basically using the uranium series, thorium series and 40K decays. It's these methods that are used to date fossil beds.

Luminescence methods, which use electrons trapped in excited states in quartz or feldspar crystals, can date materials upto a few hundred thousand years old. They're no good for dating fossils, but can provide an independent cross-check on 14C dates and extend chronologies back from them. Events that leave annual or seasonal records can also produce dating evidence. This would include tree-rings with one ring each year (and variations on ring size depending on the environmental conditions each year) which with trees giving overlapping dates can take us back in time a few millenia. Similar patterns in glaciers (reflecting seasonal influxes of fresh snow) or lake sediments can do the same. Again, no good for dating fossils but further independent verification of 14C dates (actually, generally they can provide absolute dates as counting rings/layers gives a precise age, and so are often used as a calibration on 14C to adjust for changes in cosmic ray flux and anthropogenic influences).

quote:
Now, my point is not to argue the toss about this but just to point out that the argument comes down to dating and that not everyone accepts the dating process based on radio active decay.
It's clearly the case that not everyone accepts dating methods based on radioactive decay. But, to reject that dating method you need to reject a large chunk of nuclear and quantum physics. And, usually that goes hand in hand with rejecting the scientific disciplines of geology (which had determined that the earth is old long before there was an absolute method of dating the past), and biology (because, again, the evidence of biology for evolution over long periods is consistent with the dating methods). And, because the fields of biology, geology and physics are basically outworkings of the scientific method, presumably they think there's something deeply flawed about the scientific method as it's failed to 'correct' the findings of these fields of investigation.

As I said, some people perversely reject practically the whole of the scientific enterprise.


-----------
* Most 14C is formed in the atmosphere, a very small proportion is formed at the surface. This doesn't affect the argument against a 'vapour canopy' because it's such a small contribution to the total. It can be an important contribution to some dating methods though. In particular surface-exposure dating which uses cosmogenic isotopes, including 14C, formed in exposed rock surfaces by the action of the very small fraction of cosmic rays that reach the surface.

Thank you for this explanation which is very accessible to this non scientist. If it is not too much of an imposition could you explain briefly if Uranium and Thorium dating work on the same principle as 14C?

Because most people define myth as non factual. I see Genesis as intentionally factual. if God says something,it is right; if Science contradicts this, then Science simply represents human folly.

I recognise that we all interpret BTW. I would dispute only the word 'arbitrarily' in Alan's post above. I have outlined what I consider hermeneutical principles elsewhere.

Why bother with further explanations? You're not objecting to the methodology but to the fact that it produces answers you don't like. If you're determined to reject out of hand any data which contradicts your pre-established ideas, why do you care what the data says?

It is patently clear from the world we see that there was no global flood as described in Genesis. Interpretations of Scripture which insist that this story portrays historical fact represent human folly.

I've not generally got a problem with carbon-dating, but when I read this I feel like there's a step missing. If there's been a dump of 14C in the last few centuries, why would that only be a problem for dating modern things?

Can you clarify, please? I take it that one reason is that ancient things aren't incorporating any further atmospheric carbon. However, I would have thought that there'd also be a problem in assuming what the base value for 14C was, if we've been altering it since before we actually had the know-how to calculate it.

Plants take up carbon through photosynthesis, converting atmospheric CO2 to sugars and other long-chain carbon molecules, in proportion to the isotopic abundances of 12C, 13C and 14C at the time. When a plant dies, that exchange of carbon stops, and the carbon in the plant becomes fixed until the plant decays (or, is eaten). Even decayed plant matter (eg: peat) doesn't significantly exchange carbon with the atmosphere in a manner that would alter the isotopic composition. A sample of wood from a tree that died 1000y ago would have the carbon-isotope ratio of the atmosphere 1000y ago, less the 14C that has decayed. A sample of wood from a tree that died 10y ago would have the carbon-isotope ratio of the atmosphere 10y ago. The complication with modern samples is that the significant swings in atmospheric carbon isotope concentrations create concentration ratios in the samples that are consistent with older (or, newer) samples as well. There are natural variations in atmospheric concentrations, following changes in cosmic ray flux, which also create problematic results (as an extreme example, if the production rate over a 100y period slowed at a rate equivalent to the decay rate of 14C then samples from plants that died throughout that century would have the same carbon isotope ratio and the same apparent age). Which is why we use a calibration curve, and produce results that show the probability of different ages based on the observed isotope ratio. Often you'd need other data to determine which age is most likely to be true (eg: if your sample was from a building that was known to exist in 1800 and one of your possible dates is 1850 you can reasonably exclude that one).
If I'm understanding you correctly, you really need at least SOME datings you can verify by other means to make carbon-dating viable. Is that a fair statement?

Presumably in the early days of the science it was tested on things whose age was already known to a reasonable degree of accuracy, in order to achieve some base points. What you appear to be saying is that recent human activity has caused greater fluctuations in C14 levels so that a reading could line up with more than one spot on the base curve.

To be so categorical suggests you have an iron clad cage to defend. If you are right you shouldn't give a toss if creationists are cretinous seeing you have the real good oil.

But lets query the geological column. When stratum are said to have been reversed, what proof is there that this actually happened?. I read that in one section of Alberta, Montana and British Columbia there is a reversal (algonkian and cambrian on top of cretaceous) that actually covers 7000 square miles.

Why bother with further explanations? You're not objecting to the methodology but to the fact that it produces answers you don't like. If you're determined to reject out of hand any data which contradicts your pre-established ideas, why do you care what the data says?

Because I'm not afraid of facts. You may know whether all lead was previously uranium? Or whether that is a fair assumption. Why is 14C not useful in dating fossils?

If I didn't argue with people I disagreed with, and you didn't, and nobody else did, there would be no Ship of Fools. Are you trying to tell me to shut up?

I give a toss because I care about truth and it bugs me to hear people ascribe things that aren't true to God. I'm not defending anything, I'm attacking (if you really must use military metaphors) -- attacking sloppy thinking and bad theology.

I don't need an iron clad "cage" (did you mean "case"?). Indeed I don't think I have one -- that's your bailiwick, from what you've displayed on this thread. I haven't seen a lot in your writings that says, "hey, I could be wrong." So to hit me with this "categorical" stuff is just a little ironic. And hypocritical. And not a small bit amusing.

Fair comment MT. I am one dimensional in some ways. The cage metaphor comes from Hugh Mackay, He suggests a phenomenon called the 'injection' myth. Essentially, we try to inject our information into other peoples mindsets. It's very frustrating as its impossible. You are unlikely to change my mind for reasons way beyond anything I post here and I'd suggest, vice versa. So glad you are amused.

A passage from Saint Augustine that really cannot be quoted too often:
quote:
It not infrequently happens that something about the earth, about the sky, about other elements of this world, about the motion and rotation or even the magnitude and distances of the stars, about definite eclipses of the sun and moon, about the passage of years and seasons, about the nature of animals, of fruits, of stones, and of other such things, may be known with the greatest certainty by reasoning or by experience, even by one who is not a Christian. It is too disgraceful and ruinous, though, and greatly to be avoided, that he [the non-Christian] should hear a Christian speaking so idiotically on these matters, and as if in accord with Christian writings, that he might say that he could scarcely keep from laughing when he saw how totally in error they are. In view of this and in keeping it in mind constantly while dealing with the book of Genesis, I have, insofar as I was able, explained in detail and set forth for consideration the meanings of obscure passages, taking care not to affirm rashly some one meaning to the prejudice of another and perhaps better explanation.

Thank you Dafyd, it is an important passage. But do you know which obscure passages from Genesis St Augustine did attempt to provide meanings for and what were his explanations for them?

The main difference between 14C and other dating techniques is that for 14C we start with a known intitial 14C content* and determine the age from the current 14C content. For other dating methods, the initial concentration of the parent is largely unknown but we know the concentration of the decay products is initially zero. ie: for 14C we determine the age from the parent isotope concentration, and for other methods from the daughter isotope concentrations.

Uranium dating measures the ratios of 238U:206Pb (4.5 billion year half life) and 235U:207Pb (700 million year half life) in minerals such as zircons which incorporate small quantities of uranium when they form but exclude lead. All the lead in the sample has thus been produced by the decay of trapped uranium. The cross check between the two uranium isotopes provides a means of accounting for any potential loss of lead from the mineral.

Potassium-Argon dating measures the concentration of 40Ar in potassium rich minerals such as feldspars, formed from the decay of 40K (1.3 billion year half life). Any argon in the mineral is lost if the mineral is heated to >100°C or so, and the date given is thus the last time the rock was that hot.

There are several other radioactive decay dating methods.

The reason 14C isn't used on fossils is that samples >60,000 years old have 14C concentrations below detection limits (and, that's for a good lab). Fossils are generally much, much older than that. And, often you can only date them indirectly (the conditions that reset the dating clocks for K-Ar or U-Pb etc - mainly high temperatures) will usually destroy the fossils. So we'll look for datable materials above and below the fossil beds.


-------
* Note for orfeo. Early 14C dating assumed an initial concentration ratio consistent with contemporary cosmogenic 14C production rates and atmospheric carbon concentrations. Calibration accounts for the effects of small changes in 14C production rates and carbon sequestration and release from reservoirs, both of which change the equilibrium 14C concentration in the atmosphere. The calibration shifts ages by, at most, 15% ... though can also introduce significant uncertainty in the determined age.

Don't cling to a mistake just because you spent a lot of time making it.
