I disagree that the non existence of some creator being (be it a force or an entity, whatever it is, not necessarily one from even human religions) can definitely be disproven absolutely, since we still don’t know what caused the big bang. If we’re able to ascertain what came before (if anything) then, yes, absolute disproval would be possible. But until then, no.
I agree that a Spinoza like creator being that caused the rapid expansion of the universe, then had no measurable impact on the material world can’t be disproven (neither can last-Thursdayism) but every man made god absolutely can be, especially when they make the claim that their gods do exert influence of the material world (which is easily disprovable)
