Despite the fact that Mars is separated from the Earth by tens of millions of kilometers of outer space, it is closely connected with the Earth. For many centuries, the Red Planet has attracted the closest attention of mankind; for many centuries it has kept the greatest secrets of long-vanished cultures and answers to questions that have worried people since ancient times. Author of the famous books on the theory of paleocontact “Traces of the Gods” and “The Mystery of Orion: Secrets of the Pyramids” Graham Hancock lifts before readers the veil of secrecy that hides the study of mysterious megalithic anomalies discovered by scientists on the surface of Mars. The research conducted by the author while working on this book irrefutably testifies: the governments of the countries that sent interplanetary stations to the Red Planet are hiding the information they received about the existence of a highly developed civilization there, which died about 20 thousand years ago. In this regard, it is not at all accidental that the United States is growing in interest in preparing the first Martian expedition - the Great Pyramids and Sphinx of Mars may conceal amazing secrets and technologies that can revolutionize our understanding of human history and lead humanity to a new stage of development.
