On this topic, I keep coming back to the assertion in Cicero (Is it elsewhere?) that the gods live in the between-cosmos area of the universe. By definition, that means there is no world, no world-system, no ordered part of the universe on which a human-shaped god could reside. By definition, the intermundia/metakosmos has no "world." Are we to imagine them floating around like bubbles? They literally would not have a spot to stand or sit in this area of the universe. That's why I have a hard time accepting that Epicurus believed gods were existent beings somehow residing "between world-systems." Quick lunch time rant for now.
I'll hopefully have a chance to address some of @Twentier's very valid concerns from my perspective this evening.
