Any supposed supreme deity who hinges the eternal fate of their own supposed creations on a wild ass guess isn’t one that is worthy of worship, adoration, or even basic respect. If a being with the sum total knowledge and foresight of literally everything can’t devise a better system that any random ass person off the street, I wouldn’t worry about it.

They either don’t exist at all, or they do and everyone is fucked because we exist in the playground of omnipotent super beings that are somehow also absurdly stupid. One of those outcomes is more likely than the other. I think you know which one it is.
