I don't believe in the existence of a creator, but I leave the idea open that there's always more to learn.
James Randi is an absolute skeptic who leaves nothing to imagination. I don't want to be THAT rigid, because then I won't be open to new ideas whatsoever.
Just because I believe something, doesn't make what I believe into absolute truth. Maybe absolute truth doesn't even exist. I don't know.
Your post above is more.... that of an agnostic than an atheist.
