It is ostensibly a book about Aliens, but it gives so much more. It seems like a niche topic and each chapter delivers concise and accessible message. The book invariably observes the UFO arena as a kind of vivarium for a range of psychological, sociological, and anthropological experiences, beliefs, conditions, and behaviors. The beginning of the UFO era dated 1947, and soon after extraterrestrials and their space craft were the most common explanation for mysterious sightings in the sky by the general public. The intriguing book provides illumination, insight, and perspective on the wider UFO phenomenon. It also analyzes, and brings to light anything remotely connected what the world identifies as UFOs, and Extraterrestrial life. The book shares an important and outstanding contribution about the ancient visitors and their influence on our planet Earth. The book explores the fascinating enigmas and mysterious artifacts our ancestors left behind, from incredible objects to amazingly accurate ancient artifacts: from the Great Pyramid of Giza and stone megaliths at Gobekli Tepe, to The Nazca Plains and mysterious structures of Puma Punku. It also provides a captivating adventure around the world and sheds an interesting perspective on the ancient Astronaut Theory. The discovery of independent life beyond Earth would have deep philosophical implications for us and our ideas of morality.
