text: Forty years ago, when the "face" was first revealed, it seemed very likely that it was not made by nature. The search for alien life and all the money put into NASA's programs made people believe what they wanted to hear. As time went on, and new technology was put into effect, the images of the mesa became clearer. In the early 2000's, it was made clear that the mysterious "face" was just an illusion. One can tell from the images of the "Face on Mars" that the mesa can appear to look like a face when out of focus. Alien life on Mars has not been proven either, so without evidence of life, we can't assume that the "face" was not created by nature.
