The term "Alien Conspiracy" refers to various theories suggesting that extraterrestrial beings, or aliens, are secretly interacting with Earth and its inhabitants. These theories often claim that governments, particularly the United States government, are hiding evidence of alien encounters, technology, or even the existence of UFOs (Unidentified Flying Objects). Many conspiracy theorists believe that incidents like the Roswell Incident in 1947, where a supposed alien spacecraft crashed, are part of a larger cover-up. Proponents argue that this secrecy is intended to prevent public panic or to maintain control over advanced alien technology that could benefit humanity.
