Prolific UFO seeker Scott C Waring claims to have found some ruined steps and a sea shell in pictures taken on the Martian surface by the NASA Curiosity and Spirit rover droids.

In postings on his website ufosightingsdaily.com, he also claims to have found evidence of hieroglyphics and alien faces carved into rocks in some of the images.

NASA said this week the chances of finding any life on Mars were much slimmer now as streaks in high areas it thought were caused by surface water, were probably cause by sand.

Despite this, Mr Waring claims to have found in recent months scores of examples of living Earth-like creatures, fossils, other ruins, and even alien humanoids.

Discussing his latest findings on his website, he said: "So, the NASA camera takes a close up of an object on the rover and in the background they catch, yeah, you guessed it, three signs of life. 

"Two of these signs are proof of intelligent life, enough to sculpt the faces of their culture into the stones. 

"The third sign was of a lower creature, a sea shell nearby.

"Now I know that NASAs motto is ‘For the benefit of all’, but really?
