If they're citing creationist websites, a bop on the head can't do any damage.
I particularly like the one a ways upthread with Carbon 14 dating on shell and wood producing dates on the order of a million years. And this is a person who actually claimed to know something about the subject.
C14 peters out at about 50,000 years, but a couple of labs are trying to push the AMS form back toward 80,000 years.
No rocket scientist there, eh?
Might hurt your bopper.
