No. Wrong wrong wrong. You have four main categories: Gnostic Theist ('God exists!'), Gnostic Atheist ('God does not exist!'), Agnostic Theist ('God exists, but we will never know for sure') and finally Agnostic Atheist ('God does not exist, but we will never know for sure').
The chrisman union wrote:I'm agnostic as I am fed up of these argument about whether god exists, and feels there are more important things to argue with.
In that case you're an apatheist.
