Show me a body or show me a craft. And do it in a way that is undeniable. This should not be that hard if the evidence actually were there. It’s a pretty simple conundrum. The obfuscation necessary to present these things as real would not be present if they were actually real.
As far as I am concerned the whole UFO phenomenon is a psy-op to keep bottom-scraping “researchers” busy, to promote the idea that the US in possision of superior alien technology (master race BS similar to late Nazi-era propaganda), and an attempt at getting other nations to waste money attempting to either “catch up” or attempt to spy on these assets. It also is a way for the military-industrial complex to go to Congree and beg for more money to combat these non-existant aliens and their phantom technology.
