Thanks for the links, I'll have to look it over.
You may well be right that people are born with strong predisposition to believe in god or not. There's a reasonable amount of evidence to show that people are at least somewhat hard-wired to believe in one way or another. It certainly could have been the case for me, my parents did absolutely everything they could to indoctrinate me with belief in god, yet by the time I was in my early teens and developing critical thinking skills, I'd already begun to have strong doubts and generate alternative (and invariably more palatable) alternatives to explaining something with "god did it."
Though, it's entirely possible that, in my case, this was more because of a strong inclination to play devil's advocate, especially whenever I detect a fallacious argument. It may have been just that the arguments made for the existence of the WT god were so rediculous that I dismissed his existence. Being that that's the only god I've ever known, it was easy to leap from that to dismissing the existence of god entirely. I don't know...
Anyways, I completely accept the possibility that god is there as it would litterally never be possible to completely disprove the idea of god (shoot, try disproving that god didn't creat the universe with all of us in it complete with false memories just 2 seconds ago) but I think it's fairly easy to arrive at the conclusion that if god exists, he's likely either disinterested or a total dick. Either way, it's practically the same as no god, since I'm not inclined to worship either of those options.
There's a program (not sure if it's made it across the pond or not, but I'd assume it has) called "Through the wormhole" (narrated by morgan freeman) that's discussed some of these topics that you might find interesting. Of course it keeps things at a relatively high level, but it definitely goes more in depth than most anything else on TV. Topics discussed are pretty varied, but there's been a few episodes on the origin of life, evolution, god, etc.
