In this newly revised and expanded edition, updated throughout with recent developments, geologist Robert Schoch builds upon his revolutionary theory that the origins of the Sphinx date back much further than 2500 BCE and examines scientific evidence of the catastrophe that destroyed early high culture nearly 12,000 years ago. Weaving together a new view of the origins and antiquity of civilization and the dynamics of the planet we live on, Schoch maintains we must heed the megalithic warning of the past and collectively prepare for future events.

Are history books giving us the whole story? Or is civilization far more complex and for older than we have been taught? Our school textbooks barely mention the 6,000-year-old Sumerian civilization, yet the latest archaeological findings at sites such as Jericho, and most recently, Gobekli Tepe in Turkey, have been dated to 10,000 BC. Civilization goes back at least another 10,000 years, if we are willing to believe what our ancestors themselves claimed.

Analyzing the historical and archaeological evidence, Philip Coppens demonstrates that there is substantial proof that our ancestors were far more technologically advanced than currently accepted and that certain cultures interacted with nonhuman intelligences. Our ancestors were clearly not alone.

For more than 50 years, bizarre events at a remote Utah ranch have ranged from the perplexing to the wholly terrifying: vanishing and mutilated cattle, huge otherworldly creatures, invisible objects emitting magnetic fields, and more. For the family living at Skinwalker Ranch, life was under siege, and no one had been able to explain the horrors that surrounded them...But maybe science could. Leading a first-class team of research scientists, Colm Kelleher spent hundreds of days and nights on the Skinwalker property.

Best-selling author and legendary conspiracy researcher Jim Marrs, who has investigated the recent financial crisis, the JFK assassination, and the national socialist takeover of America, now takes on his biggest subject: the history of mankind. Offering mind-blowing information that will radically alter the way we think about the world and our place in it, Marrs goes beyond the revelations of his classic Alien Agenda, interweaving science and authentic archaeological finds with provocative speculation to show how human civilization may have originated with nonhumans who visited earth eons ago.

Built at the end of the last ice age around 9600 BCE, Göbekli Tepe in southeast Turkey was designed to align with the constellation of the celestial swan, Cygnus - a fact confirmed by the discovery at the site of a tiny bone plaque carved with the three key stars of Cygnus. Remarkably, the three main pyramids at Giza in Egypt, including the Great Pyramid, align with the same three stars. But where did this ancient veneration of Cygnus come from?

"Something here really stinks to high heaven," writes Erich von Däniken. "In Twilight of the Gods," says von Däniken, "I document precisely what it was that left the first visitors breathless as they stood before the mighty stone blocks some 400 years ago.

Uncovering compelling new evidence, Egyptologist Robert Bauval and astrophysicist Thomas Brophy present the anthropological, climatological, archaeological, geological, and genetic research supporting a hugely debated theory of the Black African origin of Egyptian civilization. Building upon extensive studies from the past four decades and their own archaeoastronomical and hieroglyphic research, the authors show how the early Black culture known as the Cattle People not only domesticated cattle but were also an advanced civilization.

Exploring more than 100,000 years of Earth’s history, Marco Vigato combines recent discoveries in the the fields of archaeology, geology, anthropology, and genetics with the mystery teachings of antiquity to investigate the true origins of civilization. Establishing the historical and geological reality of Atlantis stretching all the way back to 432,000 BCE, he traces the course of Atlantean civilization through its three empires, revealing how civilization rose and fell several times over this lengthy span of time.

In his main work, the best-selling Worlds in Collision, Immanuel Velikovsky gave a detailed reconstruction of two global natural catastrophes based on information handed down by our ancestors. He mentions there that, as part of his intensive research, he found numerous indications of even more catastrophes that took place earlier in the history of mankind.

Atlantis and Other Lost Worlds is the most up-to-date and comprehensive investigation of history's infamous sunken city. Nowhere else will you find a more dramatic and convincing presentation of the evidence for its archaeological reality.

A few years ago, Mark Adams made a strange discovery: Everything we know about the lost city of Atlantis comes from the work of one man, the Greek philosopher Plato. Then he made a second, stranger discovery: Amateur explorers are still actively searching for this sunken city all around the world, based entirely on the clues Plato left behind.

Today's view of history cannot account for ancient anomalies, such as the Pyramids and advanced knowledge contained in India's Vedas. But in 1894, an Indian sage gave us an explanation not only for our hidden past but for the trends of today and for our future enlightenment - the 24,000-year yuga cycle.

Around 6000 BC, a revolution took place on Orkney and the Western Isles of Scotland. An outstanding collection of stone circles, standing stones, round towers, and passage mounds appeared seemingly out of nowhere. And yet many such monuments were not indigenous to Britain, but to regions of the Caspian Sea and the Mediterranean. Their creators were equally mysterious. Traditions tell of the Papae and Peti, "strangers from afar" who were physically different, dressed in white tunics, and lived aside from the regular population.
