Former NASA astronaut and moon-walker Dr. Edgar Mitchell — a veteran of the Apollo 14 mission — claims aliens exist.
He says extraterrestrials have visited Earth on several occasions — but the alien contact has been repeatedly covered up by governments for six decades.
Mitchell, 77, said during a radio interview in Birmingham, England, that sources in the federal government who had had contact with aliens described the beings as "little people who look strange to us."
He said supposedly real-life ET's were similar to the traditional image of a "small gray" — short, slight frame, large eyes and large head.
Mitchell also claimed human technology is "not nearly as sophisticated" as the aliens' and "had they been hostile," he warned "we would be been gone by now."
