It's funny how someone calls a belief in God a guess, without evidence, then goes on to try to discredit that "guess". Why do they do that? I know why. Do you? It's in the Bible. It is the reason every person rejects God. And it has nothing to do with belief.
A "belief" that a GOD exists...IS A BLIND GUESS.
A "belief" that no gods exists...IS ALSO A BLIND GUESS.
We humans do not know if gods exist or not...and the evidence that there are gods...or are no gods...is so ambiguous we can only make blind guesses on the issue.
Sorry you are having so much trouble with that.
It happens.
