I think you can take out the "God or" in the definition of atheism. Atheism doesn't mean you don't believe in just one god, it means them all, so it should be:
"the belief that gods do not exist"
Once we get a rules page up we can write an F.A.Q with definitions. My contribution:
Agnosticism
The philosophical view that certain truths are unknowable.
Gnosticism
The philosophical view that certain truths are knowable, or known by certain people.
Should be emphasized that neither of the above are positions on the existence of God, merely the position on whether we can know the existence of God for certain.
