All things being equal, the simplest solution tends to be the right one. - Occam's razor
I believe they have more than met the burden of proof with overwhelming number of credible documents, testimonials, photographs, videos, and chronological historical alignment with the increase of UFO sightings/visitation and Nuclear Proliferation. The testimonials alone are enough to debunk the debunkers, as those people have nothing to gain and everything to lose by coming forward. What would motivate them to be placed in the spotlight, ridiculed, discredited, and possibly physically threatened?
As a former USAF aircrew, our MADAR systems tracked UAP or UFO's flying in excess of 4-6K miles per hour or at virtually unrecorded speeds. We agreed as a crew never to report them. There was no point in saying what the military already knew, and subjecting ourselves to hours of interrogation that would ultimately result in our denying we ever recorded anything.
The irony is that humanity appears to be in more danger from within than from without. It should not come as a surprise, that a species who kills over 4 billion of its people in approximately 15K wars over the past 10K years of recorded history would seek to militarize space or create a hostile environment through the use of fear.
I highly recommend this film to everyone.
