Given the number of “evolution in the gap” arguments made by evolutionists, there seems to be a lot of “we don’t know” floating around on their side, too. And, by the way, part of “science” is to criticise faulty theories (such as those proposed by evolutionists) as part of the falsification process, which is why evolutionist arguments that “creationists only criticise” are bogus. You could make the same accusation against people who debunked the phlogiston theory or the aether, and be just as wrong, from a philosophy of science perspective.
