A few random thoughts on this entire thread:
1) No one can prove or disprove God's existence or non-existence, period. Yet, confronted with a lack of evidence it would seem the default position would be to suspend belief, hence agnosticism is the most scientifically and logically correct viewpoint. I've never heard of any atheist that actually says that she/he can PROVE God(s) doesn't exist.
2) A belief in God is a leap of faith, period. Yes, there is what can be called "circumstantial evidence" for God's existence, but that very evidence can be looked at in more than one way. For instance, many point to the fine tuning of the the fundamental forces of nature as circumstantial evidence for divine creation (unfortunately, fundamentalists will mistakenly call this "proof"). But that is not the end of the story. It's just as possible that there are an infinite amount of universes each with different laws of nature. Ours just happens to be one of the ones that can support life. And there are other ideas to explain the exquisite nature of our universe (ie the weak anthropic principle, etc.)
3) Many equate a belief in God to a belief in the Christian God. Why is this? Culture. That's the only thing I can think of.
4) For the believer in the Biblical God there are a cornecopeia of intellectual, moral and philosophical dillemmas which present themselves. I challenge any Christian to defend Yahweh's destructive actions against men, women, children and beasts in the Old Testament. Doubtless, if one saw the sanguinary verses of the Book of Judges in, say the Koran, the Christian would be appalled. But, since it is in the Bible they try and come up with ingenious ways of manufacturing a justification for such reckless acts. For this reason among a myriad of others, I cannot be a Christian and I feel, if there be a God, it is blasphemous to connect him to the such a book.
