text: In conclusion, the face was just a natural landform. The face was not made by aliens, it was just a natural landform, which are common in Cydonnia where the face appeared.      As a scientist at NASA, I know that this "face" found on Cydonia is just a natural landform that makes the shadow of a human face. Natural landforms often make shadows when light hits it at a certain angle. This causes the shadows to form things like faces, animlas, or other things. For example, when Viking 1 spacecraft was circling the planet, taking photots of possible landing sights for its sister ship Viking 2, it spotted a shadow likely to be of a humans face. The shadow made it look like an Egyptian Pharaoh.
