We have no idea if there has ever been two people with the same fingerprints. It’s never been tested and there’s no way to test it since the majority of people who have existed are now dead.
Do you understand that your logic applies to both and is meaningless. I changed three letters and it still makes perfect sense. You can’t label things as myths because edge cases might exist somewhere in the known universe.
But please, if you don’t want to interact with me, I invite you to not reply.
