Aliens were created by Western governments in the 1950s who were trying to hide actual bad-*** technology from all of the amateurs perusing the skies looking for bad-*** technology. Post-world war II there were 15 million veterans coming off of college, working union jobs, and getting ready to retire early needing something to do. We had a moderately intelligent, military trained society in America, UK, France and Russia. And 1957-1990 saw the greatest advancement of technology in Human history, especially aviation tech...so government encouraged the UFO is aliens conspiracy, even leaking alien encounters that for some reason always happened at air force bases. So retired, former military, aviation enthusiasts were now thinking this bad-*** tech were aliens instead of stealth bombers or hyper-sonic spy planes. Society is now not moderately intelligent and is not military trained and find the conspiracy of aliens all too inviting even without evidence. At the same time we have a drone revolution where new UFOs are being designed and tested every month in every developed nation on the planet.
