Lol, I'm loving these debates in the comments "are they the same person or not" when the answer is obviously both. At one point, they were one, then they weren't. It's selfcest and it's poly.
Essay time: If you make two items, and in this hypothetical you can make them perfectly identical down to the exact amount of atoms and energy stored in them, are they the same item? If your answer is "no" because they are different by being two items and not one, let me say that you don't have the same atoms you did 10 years ago but that was distinctly you, correct? (Hello, Ship Of Theseus)
If you say yes, I'll tell you no because there is two of them, and by existing in separate spots in space they receive and experience different energy loads via temperature and kinetic energy impartation and from the very start of their existences they had already diverged even if they were created at literally the same time.
They are the same person, by argument that they shared a common history but now one is different because of the nature of change over time, yet they are also distinct people because they are together but not literally the same object occupying one spot in space and experiencing the exact same thing.
