Proof of an Alien on Mars?

This amazing picture has been released across the media. The Spirit rover spacecraft has captured a photograph of this strange object on the surface of Mars. It is vaguely humanoid and it is sitting or standing in a leant-back posture with its arm stretched out. On the other hand it could be just a strange-shaped shadow or rock. There's a simple way to find out and it surprises me that nobody in the media has suggested it: Look at another picture of the same area and see if the object has moved or gone. If it has not then it's probably just a rock. If it has then it may well be alive!

Could this be a mistake by NASA? I've already spoken of how NASA and other space agendies supress information of what lies out in space, including doctoring photographs. Maybe this was one that was never meant to be published, but the NASA censor accidentally put it in the out-tray instead of the shredder. The compositor might have missed a bit with his airbrush! That would explain why they haven't taken up my suggestion and released a second photograph.

Life on Mars, the magic phrase of science fiction! Since the Mariner and Viking probes revealled Mars to be an freezing, airless dustbowl (If NASA are being truthful!) hopes of finding life on the Red Planet faded. But then came the famous Mars meteorite, with its fossilized amoebae. Microscopic bugs were exciting enough, but if this were true it would surpass it by a factor of 100! A complicated, multicellular animal creature on Mars! how is that possible when there is no liquid water and little oxygen? It could be that this being is not carbon-based and the chemical reactions of its biology are totally different to those of Earth.

Someone suggested to me that this is a figurine created by the artist of some extinct Martian civiliation. If this is so then why did they leave it lying in the middle of nowhere? Wouldn't they put it in a safer and more prominent place? I'd expect to find it in Cydonia or Tithonia, not Gustav crater! If it is just a rock then why hasn't the arm-like spur eroded over the billions of years since it fell there?

I'll be watching this story and I'll keep you posted!
