I dunno, is that really analogous? The werewolf question would barely alter your behavior even if you did believe in them.
If you're saying that you do not act as if a God existed, I call that atheism. To me belief isn't a matter of profession, it's a matter of altered behavior. By this standard a lot of so-called believers actually aren't, so this is perhaps controversial, but I think this clarifies things.
0 religious beliefs, but "There exists a benevolent (albeit highly ironic and humorous) higher power in the (uni|multi)verse.", taken as a working hypothesis, seems to be useful. YMMV
If you consider how much we don't know, the "creation story" just happens to be a very small fraction of that.
Religious people put a lot of weight on the creation story. It's not important. It's perhaps one of those things that people tend to wonder about, but in terms of scientific knowledge and the benefit of doing science to make the world better, figuring out exactly how the universe created is pretty much a useless undertaking.
The important fact is that the universe exists and has properties that can be understood through science. It is not even relevant whether it ever did not exist. It simply does, and for human purposes it always will.
The idea of the universe not existing is borrowed from religion. Scientists have come up with some fun theories, but there are a lot more useful/practical/interesting areas of science to think about than trying to come up with a scientific alternative to religious cosmogenesis myths.
