Well, I certainly do not belong to any religion, so that can be excluded. I wouldn't call myself atheist since I do not openly deny that a god could exist (or at least that's what I've tried to convey), however I also do not deny that a god might not exist. As of right now, no tangible evidence can be used to argue that a god does or does not exist.
Still, I see what you mean about the statements of belief; that was the wrong word to use. I believe not that a god does or does not exist, but rather, I believe that we cannot know whether or not a god exists. As such, you could say that I am 'undecided', but I don't plan on making a decision any time soon, since neither argument (a god exists/a god does not exist) can be proven.
That is why I try to stay out of religious debates. Neither atheists nor religious believers can win in such debates, since neither side can produce real evidence that disproves the other side's claims.
