C 14 dating10/7/2023 I see mainly vague statements like “every measurement has some degree of uncertainty” and nitpicking about an analogy. It’s a real problem and we don’t know the answer, but the plethora of dating methods which prove these samples to be old means there must be some explanation.īecause I can’t make out from the responses in the relevant thread. It exists but a few trivial assumptions will explain it. It doesn’t exist, creationists are making it up Firstly, what is the scientific view on this problem? The most recent being the thread /u/JohnBerea: "An argument I find particularly embarrassing" is one where he doesn't understand radiometric dating measurements New York: Academic Press, 212 pp.It is now repeatedly that I’ve heard creationists make the claim that 1) fossils 2) coal and 3) diamonds contain more C14 than can be explained under our current understanding of their age.
