We Are Not Alone: The Extraordinary History of UFOs and Aliens Invading Our Hopes, Fears, and Fantasies

Do you want to believe? Explore our fascination with UFOs and extraterrestrial intelligence through exclusive interviews, archival photos, and strange but true stories from history.

“We Are Not Alone . . . manages to be highly entertaining and easy to read, yet fair, balanced and thorough.” – Christopher Mellon, former Deputy Assistant Secretary of Defense for Intelligence

After decades of cover-ups and denials, in a June 2021 report, the US government finally admitted what many people already knew: yes, UFOs are real, and no, we don't know what (or who) they are.

Weird historian Marc Hartzman separates documented history from speculation as he investigates the famous sightings, strange encounters, theories, and government investigations that have shaped our ideas about visitors from beyond Earth. Revisit Roswell and Area 51, Project Blue Book and UFO reports at nuclear sites, the Betty and Barney Hill and Pascagoula abduction stories, ancient-alien theories, the mysterious Wow! signal, the interstellar object ‘Oumuamua, and much more.

Packed with archival photographs, exclusive interviews, and firsthand accounts, We Are Not Alone examines not only what people have seen and reported in the skies, but what our fascination with aliens reveals about our hopes, fears, science, governments, and culture. Accessible enough for the UFO-curious and comprehensive enough for longtime enthusiasts, it's an entertaining guide to one of humanity's greatest unanswered questions: Are we really alone?
