Reply to comment by RedBaronBob in what are your thoughts on parallel universes? by Available_Opening_98

There are two scientific theory that get cited when "almost the same Earth" comes up.

  1. Is the multiworld hypothesis where every quantum event splits into two different worlds so you have alternative realities where everything that could happen has happened.

  2. The other is that in an infinite Universe there is enough variety for almost the exact Earth to have evolved the exact same except for some tiny variation. Every possible variation exists somewhere out in infinity.

Not quite what some mean by parallel Universes.
