If you are an atheist who does not acknowledged the possible existence of a god, or gods, then you deserve a badge of stupidity.
You are making a claim based on no evidence, not an assumption.
A smart atheist assumes there is no God, for whatever good reason, not declare God(s) an impossible thing. There is no proof that there are no deities. The thing is there is no proof they exist either.
