Idk if you could call them human either lol it's a weird argument to make either way. Their has never been a situation like this irl anyway so idk you could argue either side effectively. I mean they were born here (some still live here) look human but different skin color and don't go by human. So idk I guess they are just like anything else so they are not alien or human. Just awoken.

Where there you go they're alien
