Think of it like a teaspoon of cocoa mixed into a cake dough—after a while, the ‘ratio’ of cocoa to flour particles would be roughly the same no matter which part of the cake you sampled.
The fact that the N doesn’t matter in a living thing—because it is constantly exchanging carbon with its surroundings, the ‘mixture’ will be the same as in the atmosphere and in all living things.
Certainly if there was such a Flood, as we maintain from several other lines of evidence and reasoning, most living things would have perished, and so we would expect a ‘cut-off’ point at this time.
In other words, going into the past, we should reach a period of time in which there is a sharp reduction in the number of specimens compared to the period just older than that, and as we went forward in time, we would expect a gradual buildup, as plant and animal populations recovered their numbers. Using the 15,000 published dates previously mentioned after adjusting them as described, he grouped them into 500 year ‘blocks’ and found a dramatic drop-off about 5,000 years ago, with a worldwide distribution (, Ed.
Obviously this only works for things which once contained carbon—it can’t be used to date rocks and minerals, for example. We obviously need to know this to be able to work out at what point the ‘clock’ began to tick.
We’ve seen that it would have been the same as in the atmosphere at the time the specimen died. Do scientists assume that it was the same as it is now? It is well known that the industrial revolution, with its burning of huge masses of coal, etc.
Our editors will review what you’ve submitted and determine whether to revise the article.
(We are not implying dishonesty here, merely showing how powerfully the evolutionary/uniformitarian concepts of Earth history influence great scientists to mould or discard evidence which appears to contradict that viewpoint.) What about modern measurements, using advanced technology such as satellites?
Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.
Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.
So it was expected that most deposits such as coal, gas, petrified trees, etc. In fact, of 15,000 dates in the journal to 1968, only three were classed ‘un-dateable’—most were of the sort which should have been in this category. [Editor’s note: The graph below was reproduced from a sketch in the original magazine.
This is especially remarkable with samples of coal and gas supposedly produced in the carboniferous 100 million years ago! Note that the data presented does not necessarily endorse a particular age for the Earth, but reveals a pattern We see, then, that far from being an embarrassment to the creationist who believes in a young Earth, the radiocarbon method of dating—when fully understood in accordance with modern atmospheric data—gives powerful support to his position.
