text: NASA explains this "face" formation on Mars as a huge rock formation . . . which resembles a human head . . . formed by shadows giving the illusion of eyes, nose, and mouth. Many skeptics believe that this "face" is proof of life forms on Mars and that NASA is just trying to cover it up. Although if this was proof of life forms on Mars then that would greatly benefit NASA so why would they try and cover it up? Well the answer is they wouldnt. If there was any proof that there was life forms on Mars then NASA would benefit greatly and they would most likely reveal that to the public as well, not hide it.
