The idea that there may be life on Mars has been around for centuries, but the theory got a dubious boost from recently released photos of the surface of Mars (taken by the NASA robot Spirit) apparently showing a human-like figure. Several Internet sites have glommed onto the image and suggested the figure could be alive.
