[General] How do universes with multiple god pantheons and mythologies work (E.g. Percy Jackson, God of War)? How are the conflicts between the mythologies resolved?

For example, the Greek, Egyptian, and Norse gods all have wildly different versions of the creation story, so how can they all be true in the Percy Jackson universe? Or the afterlife. Each of these religions have their own gods of death/underworld, but they all somehow exist concurrently. So which afterlife is the "real" one? Etc.

Speaking for the Percy Jackson universe, they're all true, can't remember if it's the first series of books or the Carter Kane books but they say when you're receiving judgment in the underworld, you see it however you want/expect to see it. So if you're a Christian you'll see St Peter and all that, but if you're an atheist you just won't see anything. So in the Percy Jackson universe they're all true depending on what you believe as an individual.
