Evidence: With all of the technology used to investigate the red planet, proof of alien life should have already been found. Jim Garvin, chief scientist for NASA's Mars Exploration Program explained, "As a rule of thumb, you can discern things in a digital image 3 times bigger than the pixel size...So, if there were objects in this picture like airplanes on the ground or Egyptian-style pyramids or even small shacks, you could see what they were!" By stating this, Garvin is saying that if there was any evidence of aliens builing this face on Mars, it would have been found.
