this is completely stupid and the same dumb logical fallacy people with no actual argument or evidence have to refer to. If something doesn't exist, you can't prove it doesn't exist other than the complete lack of evidence.
God existing is not the default setting. People make the claim god exists, go around trying to telling people god exists or shove their religious on others, it is on them to prove the existence of god.
But as we see all the time with those that believe in god, all they have is logical fallacies and changing the rules when it suits them, as well as holding non believers to higher standards of proof while they offer nothing. An example of changing the rules is the people that argue something couldn't come from nothing, but conveniently that rule doesn't apply to god
I don't get why believers even try to engage in an argument, they have no facts, logic or reasoning on their side, the entire basis of religion is faith and belief. So there is no proving their belief. honest, decent people would just say I believe and not even bother saying anything else, instead of trying to tell others their belief is absolute truth
