I'm Atheist-Agnostic.
Which basically just means Atheist.
The full explanation is:
I can't be certain whether one or another religion is true or not (and perhaps this is something I could never be certain of), however given my understanding of the world I choose to believe that it is significantly more likely that no religious story is true, than that one is true.
I still consider it a belief, I can't prove that no spirituality exists or not, but in the same way I don't think anyone could prove that, its simply outside the range of science. Until someone figures out a way, this is the stance I'll take.
