Certainty is a fool’s errand. Everything is ranges of probability. I ultimately can’t prove that everyone on the Internet is not a corgi, but it’s highly unlikely.

I specifically disbelieve the Judeo-Christian god exists because that god is claimed to be all-knowing, all-powerful, and merciful. All three are difficult to reconcile with the suffering we see in the world. If he knew everything and was merciful, but powerless to do anything, that would be different. If he was merciful and powerful, but didn’t know any better, that would be different. If he was powerful and knowledgeable, but didn’t give a shit, that would be different. All three, however, is a different matter.

Could there be some other explanation? Perhaps. There have been pages and pages written on that very subject down through the centuries. I’ve found those explanations to be deeply unsatisfying. It’s more likely that such an entity does not exist.

I haven’t gone through every single god in every single pantheon and measured out their likelihood of existing or not. I merely find the concept of a god to be unnecessary to explain the universe around us, so I’m agnostic about the vast majority of them.
