that all sightings are man made and are test flights.
if there were aliens in the region of the universe they would have smashed us into oblivion. not trying to evade us or "hide".
The F18 pilots thought it was theoretically possible that they were seeing drones made by Americans. Untill two F18 planes nearly got hit by one. No drone operator would have permission to fly in such dangerous ways.
Almost causing lethal crashes.
That to them then ruled out they were operated / made by some branch of the American armed forces network.
(The risk aliens might be very hostile seems real to me. It might be extremely risky for mankind to actively seek contact with advanced species)
