The best reason for not believing in a literal god is not really even the absurdity of such a proposition, and it is absurd, but the fact that we know why humans invent gods. We know the reasons, from the biological predisposition to parent-child bonding instincts, to the psychological need for ultimate explanations and the generation of their metaphorical expression, to the group dynamics of social cohesion.

Science understands the reasons gods are invented and persist in our species. This knowledge preempts any need to grapple with proofs or disproofs of literal gods. We know where gods come from and how they are made.

You make a very good point.

This is an old rabbinical argument. One of the things I like about Judaism (along with the food), is that it promotes ideas that challenge religious belief. Judaism has as much to answer for as any other religion and has caused much death and oppression, but I do appreciate a religion which says "think about this - it might lead you to abandon religion." Being Jewish is probably a large part of why I'm an atheist.
