You write "God" (capitalized). What god are we talking about here? Atheism and agnosticism are about gods in general, not just one god or one type of god (such as a creator-god).

If you make it general, such as any god or gods, then I would be square on #4, with an asterisk. That asterisk would read that I'm not 100% uncertain about what I believe (I know what I believe), I just have no belief either way and don't care to. I don't believe a god exists nor do I believe no gods exist -- and I'm agnostic.

If the scale is based on the Judeo-Christian god, then I'm a 7 (6.99... to be technical).
