The mission saw the first two people land on the moon – Neil Armstrong and Buzz Aldrin – in 1969.
However, prior to landing on the lunar surface, the team, which also included Michael Collins, orbited the moon in their spacecraft.
The astronauts aboard spotted strange craters, which startled them and prompted strange discussions.
However, the terminology the astronauts used has people believing they spotted evidence of aliens.
Mr Aldrin said: “That’s a spectacular crater.”
Mr Collins replied: “Boy, there must be nothing more desolate than to be inside some of these craters, these conical ones”
Mr Armstrong continued: “People that live in there probably never get out.”
Mr Collins then exclaimed: “Oh God, look at that Moltke (crater); he’s my favourite. Look at that son of a bitch.
“You see all those roads – triangular roads leading right past him?”
