The Story of UFO: Too Hot To Handle

Some conspiracy theories argue that various governments and politicians globally, in particular the United States government, are suppressing evidence that unidentified flying objects (UFO) are controlled by an extraterrestrial or "non-human" intelligence, or built using alien technology. Since the 1980s, such conspiracy theories often argue that world governments are in communication or cooperation with extraterrestrials, and some claim that the governments are explicitly allowing cattle mutilation and alien abduction. Mainstream scientists, government investigators, and skeptics maintain that little or no evidence exists to support conspiracy theories regarding alien visitation. Despite claims of cover-ups, conspiracy theories about alien spaceships largely lack verifiable proof, relying instead on speculation, anecdotes, and misidentified surveillance technology.
