I feel I'm starting to lean a little towards the agnostic side, but I would still call myself an atheist. It isn't quite as simple as a yes/no question, if you've actually studied philosophy you'll find that there is just as many cogent arguments for the existence of a God then there is for the non-existence of a God. I mean granted the concept of a God just seems ridiculous, but then again it seems almost as ridiculous to suggest this incredibly complex world we live in was created basically in a giant explosion. William Paley said it best; if you find a watch you know that it has been created by a creator with a definite purpose in mind, so why think differently when you see a rock for example? Don't get me wrong though, I was born an atheist and I'll die an atheist. And there are perfectly good scientific explanations for the existence of the aforementioned rock. But, all I'm saying is, it is easy to see why people become agnostics, it really isn't a black and white argument.
