Okay, this is something I just realized. If we're all descendants of Adam and Eve, does that mean we're ALL born out of incest? Because Adam and Eve were considered to be brother and sister. And even if they're not, their kids probably practised incest because they're the only parents in the world, there isn't anyone else's kids to populate the earth with. Also, Adam and Eve were probably black. They were from Africa, so yeah. So where did all the white people come from? Think about it.
