There's a rumor that circulates amongst the custodial beings that maintain the gutters between universes. This is what they say:
The first divine words spoken within during the creation of every universe are actually an element of the creation, functioning like randomizing seeds. (Ours was "let there be light," which is actually devoid of any direct meaning.) Supposedly the happiest universes to exist in was seeded with "what now".
Those gutter beings talk a lot of shit, though.
