First, I should say that I'm a Christian, so I believe the same basics that they are trying to prove. So I should like the book, but I don't. My problem with it is that they argue for a literal six-day creation and reject evolution. Once they've gone down that route, they lack credibility and anything else they say doesn't carry any weight. And also, some of their evidences are very week. My copy is a few years old, so perhaps they've abandoned young-earth creationism by now, but I doubt it.
