Except for the fact that he very clearly is lying, because there is precisely zero evidence to support the claim that the earth is only a few thousand years old.
You finding reality “abhorrent” because it shows that a literal interpretation of the Bible is clearly untrue can not change the facts. Guess what? When the truth and what you claim about God conflict, then the truth takes priority, no matter how “left out” you fantasize that makes God.
In other words, he starts from the assumption that the earth is only a few thousand years old and tries to stretch the data to fit that narrative. Yeah, that’s called lying.
Wailing “back in my day, people believed all sorts of nonsense” is not much of an argument.
