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.

Traditionally, Americans learned in school that the ancestors of the people who inhabited the Western Hemisphere at the time of Columbus' landing had crossed the Bering Strait 12,000 years ago; existed mainly in small nomadic bands; and lived so lightly on the land that the Americas were, for all practical purposes, still a vast wilderness. But as Charles C. Mann now makes clear, archaeologists and anthropologists have spent the last 30 years proving these and many other long-held assumptions wrong.

Erich von Däniken's Chariots of the Gods is a work of monumental importance---the first book to introduce the shocking theory that ancient Earth was visited by aliens. This world-famous best seller has withstood the test of time, inspiring countless books and films, including the author's own popular sequel, The Eye of the Sphinx.

While Graham Hancock is no stranger to stirring up heated controversy among scientific experts, his books and television documentaries have intrigued millions of people around the world and influenced many to rethink their views about the origins of human civilization.

The fate of the Lost Ark of the Covenant is one of the great historical mysteries of all time. The Bible contains hundreds of references to the Ark's power, but the Ark itself mysteriously disappears from recorded history sometime after the building of the Temple of Solomon. After 10 years of searching through the dusty archives of Europe and the Middle East, Graham Hancock has succeeded where scores of others have failed. This intrepid journalist has tracked down the true story behind the myths and legends - revealing where the Ark is today, how it got there, and why it remains hidden.

In the classic Our Haunted Planet, John A. Keel brings into chilling focus strange truths about the Earth and its mysterious inhabitants. Could an unseen, prehuman race have taken careful measures to remain hidden from surface dwellers? Are they still watching us from their secret hiding places, manipulating and misleading us, using us for their own entertainment, and controlling our actions?

Forty years after the publication of Erich von Däniken's Chariots of the Gods, Philip Coppens revisits the question of whether "ancient aliens" contributed to the birth of human civilization.

This examination of Atlantis shows the congruency between mythological accounts across the globe. The legends, folklore, mythology, religion of all cultures reference very similar fantastical events on lost ancient empires, extraterrestrials, giants, dwarves, supernatural beings, and many things hidden and secret. This book aims to present the tangible evidence for these myths.

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?

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.

In ancient, pre-literate cultures across the globe, tribal elders had encyclopedic memories. They could name all the animals and plants across a landscape, identify the stars in the sky, and recite the history of their people. Yet today, most of us struggle to memorize more than a short poem. Using traditional Aboriginal Australian song lines as a starting point, Dr. Lynne Kelly has since identified the powerful memory technique used by our ancestors and indigenous people around the world.

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.

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.

In 1922, Howard Carter peered into Tutankhamun's tomb for the first time, the only light coming from the candle in his outstretched hand. Urged to tell what he was seeing through the small opening he had cut in the door to the tomb, the Egyptologist famously replied, "I see wonderful things". Carter's fabulous discovery is just one of the many spellbinding stories told in Three Stones Make a Wall.

"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. I will show you what archeologists discovered hundreds of years ago and demonstrate how much has been destroyed over the centuries. Intentionally.

Greatly expanding on his blockbuster 1421, distinguished historian Gavin Menzies uncovers the complete untold history of how mankind came to the Americas - offering new revelations and a radical rethinking of the accepted historical record in Who Discovered America? The iconoclastic historian's magnum opus, Who Discovered America? calls into question our understanding of how the American continents were settled, shedding new light on the well-known "discoveries" of European explorers, including Christopher Columbus.

Tracing the migrations of the Denisovans and their interbreeding with Neanderthals and early human populations in Asia, Europe, Australia, and the Americas, Andrew Collins and Greg Little explore how the new mental capabilities of the Denisovan-Neanderthal and Denisovan-human hybrids greatly accelerated the flowering of human civilization over 40,000 years ago. They show how the Denisovans displayed sophisticated advances, including precision-machined stone tools and jewelry, tailored clothing, celestially-aligned architecture, and horse domestication.

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.
