We are not alone. And we never have been . For years we've been taught that human progress has been a long, slow climb from the primordial ooze to hunter-gatherers to empires. But what if that's only part of the story? Bestselling author and legendary conspiracy researcher Jim Marrs takes on his biggest subject yet: the history of mankind. Our Occulted History overturns conventional knowledge and beliefs, presenting compelling evidence that the earth once hosted prehistoric civilizations of nonhumans, using technologies that very well may have surpassed our own. From the flying shields reported by the Romans to the mysterious airships of the 1800s and the UFOs of today, Marrs argues that someone other than us is still present on this planet. But are these visitors simply observers--or do they play a much more active and controlling role? Jim Marrs raises this shocking question and more in the provocative and persuasive Our Occulted History.
