Probably as well that I managed to miss this thread when it first started up, or I would easily have wasted a lot of the last 2 days! I can identify well with Hullexile's route of fundamentalist atheist (my parents sent me to Humanist Society Sunday school back in the 1960s), after which I sort of migrated through philosophical and later more "spiritual practices" new-ageism to theism of the definitely christian stripe.
I freely confess that I do not understand all the God stuff. If I did, I would have a mind/intelligence/ consciousness greater than God's, which is daft. Same kind of thing as expecting the fleas on the local feral cats to understand me and what I do in my office, only more so.
I do know that man's increasing understanding of biology is making classical Darwinian evolution theory increasingly untenable as we learn more about even simple cell structure, let alone about viruses, RNA and DNA ... not only do the probabilities involved for the necessary historical mutations generate numbers which make inches in a light year look comprehensible, but we have also learned that natural selection involves reducing the amount of genetic material, not increasing it. I'm aware that there are various other theories out there, but a divine first cause is thus far - to me at least - the least unlikely scenario for the world in which we find ourselves. People like John Lennox and Ravi Zacharias explain this stuff much better than I.
So if I had a car I would want a bumper sticker saying, "I don't have enough faith to be an atheist."
As far as my fellow humans are concerned, I don't mind what beliefs you hold as long as you have genuinely worked through the options for yourself, and don't merely parrot what you hear around you, whether it's from the Dalai Lama, Ian Paisley, Stephen Fry, or ... ...
