Ummm, we don't understand (as much as we think we do) the absorption of C14. Perhaps there is a mechanism which can 'contaminate' fossils.
I believe that all scientist should feel free to go after their hypothesis, but I dislike that the possibility that evolutionist are wrong about the dating of the Earth is not further studied by evolutionist themselves.
I dislike that their initial thought is that it MUST be contamination and that they won't invest the same amount of thought into the possibility that they might be wrong.
This is the essence of the rift between the two groups, if you ignore the spirtitual aspect (which may or may not apply, as there are Christians who believe in evolution).
