Roswell Conspiracies: Aliens, Myths and Legends On the show, the Roswell UFO Incident which is part of a conspiracy theory is portrayed as being a man made phenomenon. It was set up by humans to deflect popular attention from the truth. The unidentified flying object was a prop; the body of a little green or grey man was a dummy; the witnesses to the crash were plants; as were the Air Force investigators. In fact the whole shadow world surrounding Area 51 was nothing but a distraction from the fact that the aliens had landed long ago and there were known incidents of their desire to attack, assimilate and/or destroy the human race.
