Here it is folk's, Mars was totally wiped out at one stage, here's a shoe to prove it

LIFE ON MARS 'WIPED OUT:

Discovery of 'lone shoe proves Martian humanoids killed off'.
Or is it just the trick of the light? We humans love to see familiar things in stuff like this so it wouldn't surprise me at all if this is a rock formed many many years ago? But why I do this is for that slight chance that it could be Alien in origin, I'd love it to be Alfred Jones' shoe from 1st street, Mars City. That would be cool.

It is clearly a shoe?

Lone Shoe on Mars?

That is the latest claim from an alien chaser who says he has found more evidence of life on Mars than anyone else on the planet. Scott C Waring, editor of ufosigtingsdaily.com, blogged the "shoe" was probably all that was left of a long-dead Martian fighter killed during some apocalyptical war. Mr Waring blogged about the discovering in an article entitled "Shoe Found On Mars, Indicates The Horror Of The Death Of A Species." He wrote: "While looking though some Mars rover photos I found a lone shoe on the edge of the crater. "This is probably a shoe of a species that was at war in long ago, the shoe being the lone evidence that the person had ever existed.

"How many times on a battle field or a catastrophic event have we seen photos in the newspapers of the shoes of the victims... alone...evidence of how hard they were hit, how fast they were taken from us? Well, this is such evidence." Other evidence of life Mr Waring has found in pictures beamed back by the NASA rovers include dead bodies, living tiny aliens, fossils, an array of animals, statues, buildings, and even a gun. The objects he founds are usually the same colour as the rocks around them. Sceptics and scientists say this is because that is all they are - oddly shaped rocks.

Mr Waring is a regular experiencer of pareidolia - a phenomenon whereby the brain tricks the eyes it is seeing familiar shapes or objects in textures or patterns such as clouds or a rock surface - they argue. Even other UFO investigators have been critical of the excitable Mr Waring for taking great leaps to reach conclusions that are simply not backed up by evidence. Mr waring reached the conclusion that the shoe - if of course it is a shoe - was the remains of a war casualty without having any further information. However, there is a long-held conspiracy theory that an intelligent species once inhabited Mars and was killed off in some ancient inter galactic nuclear war.

Heres a really good video about humans on Mrs in 1972.
