I think one of the reasons they picked this place to settle us on is because it's a lot like Earth. Makes it a little less of a culture shock.
Anyway, the Infinity Stone that brought you and me here brings people all across from different realities, even stuff that was fiction on our world, like Star Wars. Hell, we're fiction to some people's realities. Where we're at now is apparently parallel to ours, though. It seems to even share a lot of the same people. So, what I'm saying is don't be surprised when some people say they recognize you. It's just something that happens here.
