Also, there is a difference between "agnostic atheists" and "gnostic atheists" --

AGNOSTIC ATHEISTS: "The existence of any gods simply doesn't make sense to me, because I see no evidence indicating that it's true. Therefore, I don't believe in deities or the supernatural unless someone can someday present reasonable evidence to me."

GNOSTIC ATHEISTS: "The fact that there is no evidence supporting the existence of gods, in and of itself, PROVES my belief that it's indisputable there are zero gods in existence. Therefore, I'm factually-correct when I point out how anyone who believes in deities or the supernatural is therefore gullible and delusional."

See the difference?

Both of these basic schools-of-thought differ from traditional agnostics, who believe, "I don't believe that any existence of gods or the supernatural can be proven or disproven, one way or the other, so it's doubtful we'll ever truly know for certain."
