Any Christ

 -on any Earth

-anyone can create their own Multiverse

-as many Universes literally as they want

-and they can continue to add as many as they want

-they can put anything in them

-change the history of what they had once put in them

-just will it

-there is a separate Multiverse per person

-and each person's group of Universes. Must always be separate from outside reality

-they must not appear in the rest of space

-these made up Universes. You can't effect Earth with them

-anyone who wants can create their own Universes from straight away
