I don't believe we have been visited either as I'm sure we would have evidence of that unless of course they were super intelligent and didn't leave any evidence.

Sharp Points says
It is hard to imagine the size of the universe so I agree we cannot be the only form of life there has to be other life forms somewhere.
Maybe they have visited and seen how destructive we are so made a hasty exit.
Elizabeth Ann says
I think I agree with you that we have more to fear from dangers here on earth than possible life forms in other galaxies.
I certainly agree that we need to fear the known in this world after the atrocities of the past few days.
