There still exists the remains of many lost worlds from the past on Mars. Modern types of cities, sites of ceremonial stone circles, partially intact highway systems and the remains of a crashed space ship of alien origin scattered amidst the rocky ground are some of the images highlighted in this book. Be advised: many of these photographs  are so revealing that you may be convinced by them that intelligent life either exists on Mars now or else once did. This idea is even more compelling when viewing the photos taken of what appear to be living beings, strolling across the vast desert. Did Mars ever have an advanced civilization?  If so, what happened to it? Might the red planet currently be the base of operations for an outsider extra-terrestrial species which holds dominion over the native population?   The findings in this book will bring us closer to answering these questions.
