There is absolutely no reason for any advanced civilization or UFO to come to earth. We have nothing of value to offer. Where would these UFOs come from? It would have to be 100's or 1,000's of light years away and to have the technology to travel those distances speaks of a very advanced entity. We are a threat to no one but ourselves and at this time headed for Armageddon because a few really stupid people are trying to murder humanity.

Fake UFO's, viruses, balloons, etc all causing angst and anxiety with the purpose of misdirection. A scared, fearful and panicky person is easily controlled and persuaded to follow the government pipers to their surprising demise.
