Founder of the Cydonia Institute, George Haas and his co-author William Saunders discussed their book, The Cydonia Codex. They believe that the ancient art and sculpture of Mesoamerica is reflected in geoglyphs of Mars, specifically as depicted in the 2001 'Face on Mars.' Haas suggested that the bifurcated Martian imagery was like a hieroglyphic writing system, and is evident not only on the Face but on other structures at Cydonia as well.

Because the symbolism is repeated over and over again, it's statistically unlikely that the images are random, Haas continued, adding that it's akin to seeing all the characters from The Simpsons on the structures of Cydonia. Saunders suggested that the structures were easier to make because of the lesser gravity on that planet, and they could have more longevity because there isn't as much erosion there.

Richard C. Hoagland of Enterprise Mission joined the discussion in the third hour, proposing that a kind of "reverse osmosis" could have taken place where early high-tech humans came to Mars and then devolved after returning to Earth. Other possibilities he suggested included an indigenous Martian species and visitors from elsewhere colonizing Mars
