Snarky saying…. "Proof is for gin and mathematics".    What we would look for is "evidence" of the existence of any sort of god or gods.   There is none.   There are only traditions, assertions, exercises in logic (mostly sadly outdated) and "personal anecdote"… .("God spoke to me") which can be dismissed as psychological phenomena. Bottom line…. 1. There is no evidence of any gods. 2. There is no necessity for any gods. 3. There is massive evidence that gods are the creation of human beings.
