Is the Atheism/Theism belief/disbelief a false dichotomy? are there other options?

Yes, we have to assume certain logical facts are true, such as the negation property. We can't ever be certain of anything; we must make some assumptions at some point. The negation rule seems to work completely universally, and without it we can't use any rules of logic to do hardly anything. So it's a necessary and reasonable assumption. Of course it could be wrong. If we ever found out it is wrong, we would have to go back to the drawing board.

We have to define exactly what the criteria for "believes" is. I'd say a decent measure is "acts as though it is true". If you don't act as though it's true, you don't really believe it.

I mentioned it earlier, but I think it's reasonable to say someone could be both an atheist and a theist, because the brain is very complex. It is capable of holding contradictory beliefs, for different reasons. So maybe it's more accurate to say you're either an atheist, a theist, or both. And of course you can change between these states.

Just don't cross the streams.
