But think of the timeline. In this new timeline in this new multiverse they were actually born on Earth-Prime so I would think writing "Earth-1/Earth-Prime" would be logical.

Also I would also like there to be an easy way to see if a character naturally existed on Earth-Prime when it was created to diffiratiate it from characters who in the future could possibly come from other universes and move to Earth-Prime.
