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 C 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. You probably have seen or read news stories about fascinating ancient artifacts.
The accuracy of the machines is not in question (especially modern ones, which are astoundingly accurate when properly zeroed in). But, any source of old carbon in the ancient environment can affect the amount of C-14 in a sample.
I understand calibration might have something to do with this, but then in the article it says in italicized words that the uncalibrated date “Must Always Be Mentioned”. CMI’s Dr Rob Carter responds: Anthony, As a fan of biblical archaeology, I was asked to address your question.
But when I read articles about the results, they never mention the uncalibrated data, which could actually be correct. I am not an expert in every subject that impinges on the discussion, but I will do my best.
I read the scientific article on the carbon dating done on the Jericho site written by Bruins and Van Der Plicht.
When I did the math from their results section of the YBP, they all turned out to be right around the year 1400 .
