text: Mars is not able to support life. There is minimal air, no water, no known food source, and it is dangerous with its extreme temperatures. If there was a civilization, when did they get there? How did they get there? Where are they now? If someone was there, then why don't we have any proof or even slight clues? There is no proof or evidence to support people living there. If they lived there, why did they create a huge '"face?" None of this adds up. Concluding that it was not man-made.
