I always thought the Pokemon theology/creation-myth was for sinnoh only and how groudon/kyogre create land/sea is for hoenn only. Different cultures, different myths. It's how there could be competing pokemon for the same creation position.
I mean, there's really nothing "reality creation" about any of Arceus' moves except for the ones that show it's really pissed off. A really pissed off, powerful pokemon can easily be worshiped in fear as something that created the world.
