You are actually right. I am an agnostic. I never have, and never would, claim otherwise.
The reason I’m an agnostic is because I don’t have the gumption; or the ego; to claim that I know the Theory of Everything. I realize that there’s still a lot about the universe and existence that we don’t know. So if I were to walk around trying to say that I knew for a fact that gods don’t exist, I wouldn’t blame you if you thought me to be somewhat dishonest… or, at the very least, presumptuous.
So no, I can’t be 100% certain that some sort of “creative force”, or whatever, doesn’t exist.
But please… tell me… why does that mean I’m not an atheist?
Just because I don’t know doesn’t mean I can’t decide whether or not I believe in a higher power… and the fact is, I don’t. I do not believe in a higher power. I do not believe that we were created by anything. I do not believe that the universe was created by anything. And because I do not believe, I am an atheist. Yes, I am an agnostic. But I am also an atheist.
You see, atheism is, simply translated, a lack of theism. And what is theism? The belief in a higher power or powers. Since I do not have that belief, I am an atheist.
