One Youtube user believes he has finally found proof of the mystical man on the moon.

He claims to have made the incredible spot of an alien figure lurking in a deep crater from images on Google Moon.

Wowforreel's video - which has been viewed more than two million times in less than a month - shows what he says could be creature walking along the surface .

The strange shape can also be seen on Google Moon at 27°34'26.35″N 19°36'4.75″W.

Wowforreel said he started investigating the shadow after receiving an online tip from another web user named Jasenko.

He told UFO Sighting Daily : "An irregularly shaped dark spot he noticed on Google Moon looks like it could be a cast shadow from a massive standing object, or figure,'

"At first I thought maybe it was something drawn into the picture but after going to Google Moon, whatever it is or isn't...uh, is there."

'It is really there, not faked and I have no clue what it is. I found nothing else like it in any of the other craters," he added.

However, the most likely explanation for the sighting is a psychological phenomenon called Pareidolia. This is the brain's response to seeing faces and other significant objects in random stimulus.

Wowforreel seems to have quite a habit of spotting strange objects in Google Moon images.

In January he drew flagged up a triangular shape that he believe to be a spaceship or secret alien base.

The images used to create the lunar images for Google Moon come from Nasa, but the space agency has yet to comment on the discovery.
