Who are we? Where did we come from?How did we get here? All the answers are here, bigger than life, and more powerful than fiction, presented by the NASA scientist whose Apollo computer program got us to the moon: -The secret of Atlantis -The significance of the Great Pyramid at Giza -The lost treasures of ancient Egypt -The puzzle of the Mayan Calendar -The truth about astrology -The world beneath the polar ice caps -Stonehenge, miracle of mathematics -The Rhodes Calendar -The Mystery of the Maltese Cross -What the Apollo and Gemini astronauts REALLY saw Using sophisticated computers, new and previously overlooked information, and his direct experience as the NASA scientist who designed and built the Apollo communications and data-processing system, Maurice Chatelain amasses starting and convincing evidence that our ancestors came from outer space. "A mathematical approach, as well as an archaeological overview... Should prove to be considerably more durable than Erich von Daniken's 'Chariots of the Gods.' A worthwhile contribution to serious students of the ancient mysteries, by a real scientist..." -The Dayton Daily News

NATIONAL BESTSELLER • “Exciting and provocative . . . A tour de force of a book that begs to be seen as well as to be read.”—The Washington Post Book World World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. Shadows of Forgotten Ancestors is a thrilling saga that starts with the origin of the Earth. It shows with humor and drama that many of our key traits—self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics—are rooted in the deep past, and illuminated by our kinship with other animals. Sagan and Druyan conduct a breathtaking journey through space and time, zeroing in on critical turning points in evolutionary history, and tracing the origins of sex, altruism, violence, rape, and dominance. Their book culminates in a stunningly original examination of the connection between primate and human traits. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, Shadows of Forgotten Ancestors is a triumph of popular science.

"Anthony Aveni reveals how !Kung and Mursi hunter-gatherers depended on signals in the sky for their survival and sustenance; how Polynesian sailors navigated a seemingly limitless watery world by star bearings; how social cohesion in cultures as diverse as the Pawnee and the Inca was mirrored in celestial imagery; and how the cosmic connection between the arrangement of Chinese and Aztec cities and the constellations served as an expression of political authority." "For most of human history, people found meaning in the dance of the cosmic denizens. Today, many aspects of this intimate contact between daily life and what happens in the sky have disappeared. Did our ancestors have an understanding of the cosmos that we ourselves lack? How and why did it all happen? These are the questions addressed in this engaging and erudite book."--BOOK JACKET.

An exploration of how acceptance of panspermia will soon change history • Offers extensive scientific proof of panspermia--that life arose on Earth via comets and that evolution is seeded by viruses arriving via comets and interstellar dust • Explores the major philosophical, psychological, cultural, religious, and environmental ramifications of the acceptance of this new scientific worldview Mainstream consensus is that life arose on Earth spontaneously out of “primordial soup.” Yet this theory, as well as the Darwinian “survival of the fittest” concept as it relates to major steps in evolution, has no scientific basis or proof. Where, then, did life come from? As the authors show, with conclusive scientific evidence, life came from space--a concept known as “panspermia.” We humans, and all other life on Earth, evolved over millennia in response to viruses that arrived via comets, and we continue to do so. Exploring the philosophical, psychological, cultural, and environmental ramifications of the acceptance of panspermia, the authors show how the shift will be on par with the Copernican Revolution--when it was finally accepted that the Earth was not the center of the Universe. Explaining the origins of the panspermia theory in the work of the late Sir Fred Hoyle, the authors reveal the vast body of evidence that has accumulated over the past 4 decades in favor of the cosmic origins of life, including viral inserts found in DNA that have shaped our human genome over millions of years. They show how the tiniest of viruses, microscopic animals (tardigrades), and even seeds have been found to be natural cosmonauts. The authors also show how space-borne viruses play a crucial role in the positive evolution of life and that our entire existence on this planet is contingent on the continuing ingress of cosmic viruses. Revealing how panspermia offers answers to some of humanity’s longstanding questions about the origins of life, the authors discuss the impact this shift in understanding will have on our relationship with the Earth and on culture, history, and religion. And perhaps the most dramatic ramification of all is that acceptance of panspermia means acceptance that Earth is not unique--that other life-filled planets exist and intelligent life is common in the Universe. Not only did we come from space, but we are not alone.
