The focus of this book is on aliens having visited or living on this Earth. There is lots of evidence that not only are aliens on Earth during the present, but have been here for thousands if not millions of years. There are lots of stories and some good evidence that this is all true. Even today there are videos of alien craft, and stories in the news about our government still studying and reporting on aliens visiting us.

This book is an overview of both the history of aliens and UFOs, as well as a review of hidden aerospace and propulsive technologies. Where did these technologies come from? And how have they developed in the intervening years? Also, I try to answer some questions of how likely some of these claims are - because some things having to do with UFOs and aliens are much more documented than others. There are also many alien-related and secret programs that most of you listeners may have never heard of. The most interesting ones are summarized here.

The product of 30 years of intensive research, The 12th Planet is the first book in Zecharia Sitchin's prophetic Earth Chronicles series - a revolutionary body of work that offers indisputable documentary proof of humanity's extraterrestrial forefathers. Travelers from the stars, they arrived eons ago, and planted the genetic seed that would ultimately blossom into a remarkable species...called Man.

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.

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.

From Graham Hancock, best-selling author of Fingerprints of the Gods, comes a mesmerizing book that takes us on a captivating underwater voyage to find the ruins of a lost civilization that's been hidden for thousands of years beneath the world's oceans. 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.

Erich von Däniken again shows his flair for revealing truths that his contemporaries have missed. After closely analyzing hundreds of ancient and apparently unrelated texts, he is now ready to proclaim that human history is nothing like the world religions claim---and he has the proof! In History Is Wrong, von Däniken takes a closer look at the fascinating Voynich manuscript, which has defied all attempts at decription since its discovery, and makes some intriguing revelations about the equally incredible book of Enoch.

Professor Timothy R. Pauketat illuminates the riveting discovery of the largest pre-Columbian city on U.S. soil. Once a flourishing metropolis of 20,000 people in 1050, Cahokia had rotted away by 1400. Its earthen mounds near modern-day St. Louis reveal “woodhenges” and evidence of large-scale human sacrifice.

In a world where rational, scientific explanations are more available than ever, belief in the unprovable and irrational - in fringe - is on the rise: from Atlantis to aliens, from Flat Earth to the Loch Ness monster, the list goes on. It seems the more our maps of the known world get filled in, the more we crave mysterious locations full of strange creatures. Enter Colin Dickey, cultural historian and tour guide of the weird.

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.

Were human beings created by powers from outer space? Did extraterrestrial giants build the megaliths of Malta and the menhirs of Brittany? Was the Ark of the Covenant a machine built by the astronaut gods? In Signs of the Gods?, Erich von Daniken travels far and wide around the globe to study the many strange phenomena that all point to one conclusion - that many thousands of years ago, Earth was visited by a race of superhuman powers and intelligence.

For at least 20,000 years, we have led not just an earthly existence, but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are - our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.

Ancient cultures around the world spoke of a vast cycle of time with alternating dark and golden ages; Plato called it the Great Year. Most of us were taught in school that the dark ages were real but the golden age was just a universal myth. But new scientific evidence suggest this cycle of high and low ages may have some basis in fact. Now that the astronomical community has discovered that something massive is tugging on our solar system the stage is set for discovering the motion that moves us from high ages of enlightenment to low ages of darkness.

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.

Graham Hancock's multi-million bestseller Fingerprints of the Gods remains an astonishing, deeply controversial, wide-ranging investigation of the mysteries of our past and the evidence for Earth's lost civilization. Twenty years on, Hancock returns with the sequel to his seminal work filled with completely new scientific and archaeological evidence, which has only recently come to light.

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.

Popular Lost Cities author David Hatcher Childress takes us into the amazing world of ancient technology, from computers in antiquity to the flying machines of the gods. Childress looks at the technology that was allegedly used in Atlantis and the theory that the Great Pyramid of Egypt was originally a gigantic power station. He examines tales of ancient flight and the technology that it involved; how the ancients used electricity; megalithic building techniques; the use of crystal lenses and the fire from the gods; and more.

"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.

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.

No other monument in the world evokes mystery like the Great Sphinx of Giza. It has survived the harsh climate of Egypt for thousands of years and will remain long after our own civilization is gone. According to orthodox Egyptology, the Sphinx was built around 2500 BCE as a memorial to the pharaoh Khafre. Yet this “fact” has scant to no supportive evidence. When was the Sphinx really built and, most importantly, why?

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.

New York Times bestselling historian Gavin Menzies presents newly uncovered evidence revealing, conclusively, that “the lost city of Atlantis” was not only real but also at the heart of a highly advanced global empire that reached the shores of America before being violently wiped from the earth. For three millennia, the legend of Atlantis has gripped the imaginations of explorers, philosophers, occultists, treasure hunters, historians, and archaeologists. Until now, it has remained shrouded in myth. Yet, like ancient Troy, is it possible that this fabled city actually existed?

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.

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.

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.
