Well, if we go back in time, when people hardly travelled, then for a white man to run into a chinese man or a black man woud hae been a very shcoking exprience an it probably was for the first indiviuals that experienced it.
Taking that line of thought, it seems more than logical to assume that there must be other beings out there that are probably far superior to us. And if they are anything like us, then some of them are probably friedly and some are not.

If they were going to do sometthing terribe I would think they would have been more secrective bout it and the fact that you are still around speaks volumes about their inten.
