Like the saying goes: I don't believe in anything. I'm a scientist.
Richard Dawkins has a great line, something like "we are all atheists, I just take it one God farther". In other words, no one believes in all possible gods, which means they don't believe in some. Most believe only in one, or a set that goes together. But, given that there are thousands, if not millions of "gods" (or trillions, if each human has their own interpretation), then you could argue that even the most devout is 99.99%+ atheistic. And given that most of us are skeptics, and a good skeptic won't believe in "no gods" either, then we are probably not 100% atheistic. Perhaps 99.99%+, though. We are all pretty much in the same place.
