Resumen o Introducción
In the early 1900′s, people looked into the night sky and believed there was, or at the very least had been, life on Mars. Intricate canal systems were thought to be seen crisscrossing the planet, and were used as evidence of a wondrous civilization.
But, Mars was millions of miles away, and when we got closer to the Red Planet, starting with NASA′s Mariner 10 mission, we learned much more. Although some still believe they have seen "an ancient city the size of Los Angeles with a geometry of streets and cross roads" ("The Cydonia Complex") or have spotted ancient pyramids and a gigantic face in the Cydonia Complex, scientists discount these reports. Rather than an amazing series of agricultural waterways, or buildings that would rival Egypt, Mars is only a giant desert, which could never support life, or could it?
