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.

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.

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.

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.

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.

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?

Built at the end of the last ice age, the mysterious stone temple complex of Göbekli Tepe in Turkey is one of the greatest challenges to 21st century archaeology. As much as 7,000 years older than the Great Pyramid and Stonehenge, its strange buildings and rings of T-shaped monoliths - built with stones weighing from 10 to 15 tons - show a level of sophistication and artistic achievement unmatched until the rise of the great civilizations of the ancient world, Sumer, Egypt, and Babylon.

What caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

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.

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.

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.

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?

"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.

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.
