Crashed saucer spotted on the moon

UFO experts have been scouring through images that were taken by a probe orbiting the moon in the hope of finding evidence that points to proof that extraterrestrials have visited or are living in bases on the moon.

One Ufologist has posted a video onto YouTube which they believe shows a crashed saucer on the moon. They also say it shows footprints leading up to or maybe away from the saucer as if someone or something walked away from it.

Looking at the video it does look very strange and it does look like a crashed flying saucer. The shadow the that object is casting also makes it seem it could be quite tall.

What do you make of it?  Is it just a rock or something more interesting?
