Could this be an alien on the Moon or just Photoshop? You decide (VIDEO)

Could this be an alien on the Moon, or just a sneaky Photoshop trick? A video posted on YouTube by user wowforreal shows pictures of what seems to be a vaguely humanoid figure striding across the pockmarked surface of the Moon, casting a shadow.

Wowforreel's video shows what he says could be an alien figure walking along the surface and it has already been viewed more than two million times in less than a month.

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

Wowforreal was also careful to post a link to an article that points out the photo could be explained in a number of ways, including as a trick of light.

'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,' Wowforreeel told UFO Sighting Daily.

'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.'

Viewers commenting on the video have attributed the figure to everything from an alien to fictional space traveler The Little Prince to Slender Man, also a fictional character. Most commenters, however, dismiss it as trick photography.

NASA has yet to comment on what could be the cause of the figure and shadow.
