>>512101200 (OP)You wouldn't have been born in the first place. Every ancestor born after the move to the Americas would not exist, because those ancestors who moved to the Americas would have had sex at a different time, meaning that the same sperm and egg cells that created their children would not meet, and thus any children they did have would be completely different people. Your entire family tree after that point would cease to exist and be replaced by something completely different, not that you'd be around to know.
