The Apollo 17 astronauts were Commander Eugene Cernan, Lunar Module Pilot Harrison Schmitt, and Command Module Pilot Ronald Evans.
Commander Cernan and Mr Schmitt walked on the Moon, while Mr Evans remained in lunar orbit.
But if the astronauts did not encounter an alien statue on the Moon, why does Mr Waring believe the rock is extraterrestrial in nature?
According to NASA, the answer could lie in a psychological trick of the mind known as pareidolia.
Pareidolia causes the mind to see shapes and patterns where they do not exist, leading many to see alien faces and UFOs in natural formations.
