The face on Mars wasn't created by aliens, in fact it has no connection to alien life form at all! When the face was first discovered no one had really known much about it so people started hopping to conclusions before anything could be proven or tested. That is until NASA started looking into this "face on Mars". The face is actually a huge rock formation . . . which resembles a human head . . . formed by shadows giving the illusion of eyes, nose, and mouth. That's it- simply a rock formation but the shadows casted upon the crevices gives the strange formation the appeal of a human face. When people began to become even more skepical, on April 8, 2001, NASA had the Mars Global Surveyor draw close enough to snap another picture of the face. The day was a cloudless summer day in Cydonia. NASA's serveyor camera had taken a crisp photo of the face in highest resolution. "Each pixel in the 2001 image spans 1.56 meters, compared to 43 meters per pixel." so you can discern things in a digital images three times better than the pixel size. So NASA, and the rest of the world, had a more clear and better picture of the face everyone was talking about. Although the face may seem strange, it could be a rather common landform for Cydonia. "What the picture actually shows is the Martian equivalent of a butte or mesalandforms common around the American West." Although this one may seem to stick out from the rest, it could merely be the shadows playing tricks on the human mind. "Scientists figured it was just another Martian mesa, common enough around Cydonia, only this one had unusual shadows that made it look like an Egyptian Pharaoh." The landform may very well be common around Mars, it's merely the shadows ghosting around the landform that causes it to look like a face! So in reality, there is no alien life form connected to this rock formation at all!
