That's my take too. And I think the reason modern believers do this is that they must have the Bible as an absolute authority, and to do so they must believe in the literal accuracy of everything contained in it. Leads to some interesting contradictions.
While I am a strong creationist, I do believe that some things in evolution do apply. There WERE dinosaurs and other ancient living things. There's no disputing that. The truth is NOBODY completely understands the process except him who did it--God.
This is one Christian who has never had a problem with science. I regard it as man's way of explaining God's processes. I hate to see the backlash against ALL science by some people because of the creationism dispute. It's SCIENCE that has given us pretty much every comfort we know today and will continue to do so in the future.
