We Are Not Alone: The Extraordinary History of UFOs and Aliens Invading Our Hopes, Fears, and Fantasies .“WE ARE NOT ALONE is a highly informative new book by Marc Hartzman that covers the UFO/UAP topic from ancient times to the present. It manages to be highly entertaining and easy to read, yet fair, balanced and thorough. Because it manages to be so enjoyable and engaging, while still doing justice to the complex history of the issue, it provides an ideal introduction to the UFO/UAP topic.”- Christopher Mellon, former deputy assistant secretary of defense for intelligence. "The study of UFOs (aka ufology) is really a study of history... but an exotic part of history that's not taught in the classroom. Now that UFO news pervades the media, I'm often asked by friends: How do I make sense of it all? They want to know how to get up to speed. Now I can finally say, ‘Just read this book.’ We Are Not Alone is the perfect summary of the most prolific UFO events and key themes of related phenomena. A fun read packed with illustrations and photos that will strike up an existential conversation anywhere on planet Earth!"- Ben Hansen, UFO researcher and host of UFO Witness" An entertaining, informative and even-handed overview of UFOs, alien abductions and the scientific search for extraterrestrial life, that places our fascination with aliens in its social, cultural and historical context."- Nick Pope, UK Ministry of Defense 'UFO Desk', 1991 – 1994“Marc Hartzman has captured the essence of the UFO subject and its history in We Are Not Alone. No one book alone can be a compressive treatise on the subject, but Hartzman has zeroed in on select narratives and topics that paint a broad overview of the diversity of the UFO subject matter as well as the culture surrounding it. Whether you're a newcomer to the topic or a seasoned investigator/researcher, everyone will find something of interest in this enjoyable read that serves as an out-of-this-world journey."- David Marler, Executive Director, National UFO Historical Records Center.
