He probably can't help but do it because he's an evangelical Christian who believes in the literal word of the Bible.
Another question is that if God really made the world and all we see, including the fossils, why was it man who had to write it all down? Couldn't have God made an HP Laserjet and printed a million copies of His holy word, and made flatscreen TV's for the Hebrews that would show how he did it all?
I'd also make attacks on the flood story, because that much water doesn't exist on Earth, that much water can't fall as rain, if there was that much rain in the air then the Earth's surface air pressure would be the same as the pressure 30,000 feet under the ocean, where a nuclear submarine would be crushed like an egg, and that it requires one to believe that all the animals in the Americas and Australia swam across the ocean to get on a boat so they wouldn't drown, just so they could swim back. In fact, it was the discovery of North and South America and their unique species that convinced the Catholic hierarchy that Noah's flood wasn't literally global, because thousands of land mammals swimming across the Atlantic and back didn't make a lick of sense.
