It's all amusingly laid out here, by someone who's been involved enough in the arena to have them pretty well nailed.
One of the commenters added this one:
The Law of Unprovable Miracles. We know that the miraculous events, like the Resurrection, described in the Bible aren't true because miracles are impossible. We know miracles are impossible because there is no proof of them. I mean, if someone was really raised from the dead, you'd think someone would write it down or tell people about it or something.
Yeah, and you'd also think God would hold off on it until the era of ubiquitous Flip video cameras. Because screw everyone else who came before: atheist skeptics are more important.
