I figure this would be a more thorough way of giving you what you need to understand rather than trying to type it all out here. If you don't want to spend the money I'll send you a copy free for nothing. That goes for anyone else who's skeptical.
For those that don't know, I have a lot of respect for Dave, and consider him a good friend, even though we've never met. However, when he posts things I believe are wacky, then I'm going to point them out.
We had a discussion a while back about the old testament telling parents to stone their children to death when they talk back. Dave said that the old testament wasn't to be taken literally, that it had been replaced by the new testament. This prompted my earlier comment since he was taking Genesis literally.
I'm very familiar with Jason Lisle, author of the book Dave posted. Dr. Lisle has been exposed for promoting junk science and is not respected in the scientific community. He's an outcast, and there's a ton of information on the web about his use of confirmation bias, lack of scientific methods and outright lies.
One of my favorite podcasts has done many episodes disproving the absurd claims of Jason Lisle. There are several episodes about him specifically. Exposing PseudoAstronomy Podcast with Stuart Robbins
