text: The 'Face on Mars' is a natural landform. The light from the sun is shone across the landform to make it look like it has two eyes, a nose, and a mouth like a human person, but, if you were to create an exact copy of Mars, put on a different scale, hold it still, and shine light at the exact angle of the sun, you would see that the sun is what really causes the 'Face on Mars' to appear to look the way it does.
