It's not a belief
you don't believe there is not a god any more than you don't believe that there is a massive hairy purple and green monster standing on your left shoulder. It's self evident that the monster does not exist, whether you consciously think about it or not makes no difference.

This
A belief is, by its nature, your support for something that cannot be tangibly proved one way or another. That's the point of faith. there are three options.

1)you believe in a god
2)you don't know or care
3)there isn't a god.

You can't believe in the non-existance of something that effectively requires faith in the first place.
