(I assume I'm replying to Buckna rather than Tony.)
Why would scientists continue to use dating methods that produced
conflicting, random dates? Assuming *every* evolutionary scientist in the
world was interested in producing false data, wouldn't such random results
be an embarrassment? Wouldn't they look for something that got a nice,
consistent date that they could fool everyone with?
Doubt cannot injure or even perturb the truth.
The truth is a citadel about which the breezes of doubt play.
