text: NASA has more than enough facts and evidence to prove that it was made naturally. The article says "Defenders of the NASA budget wish there was an ancient civilization on Mars." This means that the landform was made by natural occurances. The landform is natural. The passage also says "Thousands of anxious web surfers were waiting when the image first appeared on a JPL web site, reavealing... a natural landform. This means that there was no alien monument after all." There is much more proof of this landform being natural than there is being made by aliens.
