UFO's? I sure hope so.
I certainly hope that the human race isn't the best and brightest lifeform in the Galaxy or Universe. Its depressing to even consider the idea.
I'd say that the reason that any inter-galactic traveler hasn't shown itself is that it looked around Earth and decided that humans are so fragile, belligerent, ignorant, dirty, self-destructive, etc. that we wouldn't even make good pets.
I think most aliens would look at us in the same way we look at the Wuhan virus.
