No, that's the case for many people. But you're not all from earth, even planet-bound. It's the thing that brought us here that is. It might make sense though, lots of earth people, the other dimensions being so close. Lots of crime, many ways to track it.
I'm not judging it. People are more than the things they've done in the past. I look at what you do when I know you.
Many species believe they are the best. Some want to kill everyone else. Others thinking us lesser use us as they wish, for their purposes. The Peacekeepers liked trapping and using mine. Grubeks harvest our neurotissue (eating it is said to increase brain function capability). Patriqu-ro kill us as competition.
