Why I am No Longer a Christian, Evid3nc3.
This is a very even handed, well put together, and well-researched story of one man's journey from born-again christian to a Bayesean Rationalist naturalist. It's very emotionally moving, and I'd recommend watching it. It totals about two hours and change in length. His story is very similar to mine, but as I don't have beautiful music or illustrations, I just point people at his videos.
Specifically, I'd recommend this video and this one from the series, explaining where the modern conception of the Biblical God came from.
