text: The first reason I believe this is because in papragraph 7 it says" Thousands of anxious web surfers were waitin when the image first appeared on a JPL web site, revealing....a natural landform. There was no alien monument after all." This part of the prompt tells that alot of people wanted to know what the faces were and they found out that the faces were natural landforms. This sentence also shows that they went out and found that it was a natural landform. That is just one of the reasons why i believe that the faces are natural landforms.
