A less absurdist challenge (not saying appeals to absurdity are bad) is to suggest that in fact Poseidon rules from the sea ( Ia! 🐙) and governs the Olympians, but it was Kronos who crafted from aether and kaos (Starring Jeff Goldblum) the silvery egg from which Phanes was born, and They, in turn, begat the universe we know today.

And this creation story was known before Adonai and His Mesopotamian ancestors were around so it has seniority. Ask them to disprove this.
