I bet this is getting pretty heavy traffic, but you should probably read this story on Anthony Flew. My favorite part is (atheist) Richard Carrier reassuring his followers that its only a minimal god Flew is believing in. No cause for alarm.
I think the interesting idea in this is that a philosopher and pretty much lifelong atheist would find that a) the evolutionary explanation for the origin of life was not credible, and thus b) there must be a god. I guess some of the traditional arguments still work.
