Aliens?

In July 1947 a suspected UFO crash-landed in Roswell, New Mexico. Extra-terrestrial debris marked in alien hieroglyphics and even alien corpses were thought to be recovered. An autopsy was believed to be carried out on the corpse of an alien by U.S. doctors. However, since the 1970s huge controversy has surrounded the Roswell incident. The U.S. military took a firm stance that it was not an alien craft that crashed to Earth but an experimental high-altitude surveillance balloon belonging to a classified program named “Mogul” instead. A cover-up to detract the public’s attention of a genuine UFO and alien life in an effort to avoid mass hysteria? Or was it simply the truth that some people do not want to accept?
