The name Creation Research is an indication of an alternative therom.
What I mean is that the ICR seems to think there’s only two theories out there, so if they can criticize Evolution enough, then “Creationism” automatically wins by default, no need to supply any proof. That’s not the way Science works - let’s see your proof before we believe.
Besides, the evidence for Evolution is vast and complex, so nitpicking about little points does nothing to invalidate the overall concept.
The Bible is a beautiful and powerful book, but it was never intended as a guide to the geological or biological history of the earth, nor should it be.
Just saying.
