Forgot to mention, I have always thought there was a term for people who didn't care one way or the other about the existence of god(s), in contrast to those who are uncertain:

If you believe in the existence of god(s), you are a theist.
If you believe in the nonexistence of god(s), you are an atheist.
If you don't know whether god(s) exist or not, you are an agnostic.
And if you don't CARE whether god(s) exist or not, you are an IGnostic.
