text: Although, I do understand why people could believe the "face" was built by aliens. It does look like it could be a monument, like the ancient Egyptians built for their people. However, life does not exist on Mars; therefore, the "face" could not be built by aliens. Also, some people think that aliens do exist on mars, and that NASA is just hiding it. But, why would NASA hide that they found an alien civilization? That could only help the company, not hurt them. And, if you still don't believe me, if there were aliens on Mars, wouldn't we be able to or have seen them by now? Once again, I say that the "face" on Mars is just a mesa that gives the illusion of a face, not a statue built by creatures that don't exist.
