I am basically an atheist, but I put "other" just to avoid semantic traps. I don't believe in anything that I call "god," but it is certainly possible to define "god" in such a way that I would believe in "him" (the universe, natural law, etc.) And I've found that oftentimes the definition of "god" used is so logically incoherent that it would be wrong to say I don't believe in it, as that would imply an actual concept to negate. Rather, they are "not even wrong," and literally speaking nonsense.
