text: In conclusion, the Face on Mars is not an alien formation. Scientists have proven this by the effect of the shadows on the rock, the fact that it is a mesa, and by there not being any artifacts on or around the formation. Therefore, this is not evidence of there being ancient civilizations on Mars. For over thirty years, the question about the Face on Mars has been posed; alien life or natural landform? Although scientists have been grilled by the media, there is only truly evidence that the Face is a natural landform, much like a butte or mesa, landforms common around the american west, despite what conspirasy theorists have to say.
