Who left a shoe on Mars?

UFO Expert Claims New Photo Is Proof Of Aliens

Perhaps we aren't alone after all.

Since landing on Mars in 2004, the Opportunity rover has beamed stunning images back to Earth that give star-gazers a glimpse into an alien world.

Now, one conspiracy theorist claims to have spotted something bizarre in one of the images, which he says depicts 'the death of a species" and suggest there once was life on Mars: A shoe.

Laying among the rocks and dirt of the red planet, they claim there is a shoe that once belonged to a species that was at war on Mars, and is 'the lone evidence that the person ever existed'.
While looking through some Mars rover photos, I found a lone shoe on the edge of the crater,' said Scott C Waring, creator of UFO Sightings Daily.
