I am an Atheist.
I believe that the supernatural is nonexistent. There is no god, no devil, no ghosts, no spirits. I believe that everything we see and experience, ultimately will have a rational, scientifically-valid explanation.
I do not believe in an afterlife and have little patience for Creationists, mystics, religious fanatics, superstition, and pseudoscience.
I don't hate religion or its followers, but I have no use for it personally and never have, even as a child.
At one point, many years ago when I was still young and stupid, I called myself "spiritual." But I'm not. I don't even know what that means. I was just afraid to call myself an Atheist.
