We live within the ruins of an ancient civilization whose vast size has rendered it invisible. Remembered in myth as Atlantis, Lemuria, or other lost world archetypes, the remains of this advanced civilization have lain buried for millennia beneath the deserts and oceans of the world, leaving us many mysterious and inexplicable clues. Investigating the perennial myth of a forgotten fountainhead of civilization, J. Douglas Kenyon presents extensive physical and spiritual evidence of a lost great culture, the collective amnesia that wiped it from planetary memory, and the countless ways ancient catastrophes still haunt modern civilization. He explores evidence of advanced ancient technology, anomalous ancient maps, extraterrestrial influence, time travel, crystal science, and the true age of the Sphinx. He examines evidence of Atlantis in the Bible and ancient Armageddon, the Stone Age high-tech found at Gobekli Tepe, the truth of Rapa Nui (Easter Island), the Zep Tepi monuments of Egypt, the mysteries of the Gulf of Cambay, and what lies beneath the ice of Antarctica. He looks at extinction events, Earth's connection with Mars, and how our DNA reveals that humanity has had enough time to evolve civilization and lose it more than once. Exploring the advanced esoteric and spiritual knowledge of the ancients, Kenyon shows that the search for Atlantis and other lost worlds reflects the search for the lost soul of humanity. Drawing upon Velikovsky's notion of a species-wide amnesia caused by the trauma of losing an entire civilization, he reveals how the virtual ruins of a lost history are buried deep in our collective unconscious, constantly tugging at our awareness. As Kenyon reveals, by overcoming “the Great Forgetting,” humanity can find its way out of the haunted labyrinth in which we find ourselves lost today and rediscover the heights of spiritual and technological advancement of our ancient ancestors.
