FUCK THE POLICE
911 EVERY DAY
I have no way of knowing. Von Daniken did raise some interesting points, but much of his work was unscientific.
I believe, if we have been discovered, we are viewed as a sort of galactic dumpster spilling garbage out around us. I cannot see any alien race being impressed with what they found here.
Again, aliens would be so radically different from us in emotion, morality, and thought that it's pointless to even speculate what they'd think.
