Many governments have publicly admitted that footage of things that have not been identified exists.
Look at this thread. People like
@gremins are convinced that a large percentage of what is contained in that footage is energetic phenomenon that is the result of an emerging mythology.
And what's even worse, is that when someone who has a bit of experience looking at infrared footage, and understands the data being displayed by the various instrumentation -altitude, speed, field of view, etc, the UFO/UAPs generally fall under 3 categories: bird, airplane, optical illusion caused by limitations of the equipment the footage was recorded on (this is the explanation for most of the black triangle "phenomenon").
But not 100% of then can be explained. So I guess there's a non 0 probability that gremlins is right and this new emergent Jungian mythology is altering the nature of reality...or whatever the fuck.
