We Are Not Alone by Marc Hartzman (Quirk Books)

This book is for anyone who has ever questioned if we are truly alone in the universe.

We Are Not Alone is presented objectively by the author. All claims of intelligent non-human/alien life in space or elsewhere on the Earth are supported by documentation, eyewitness accounts, and photographic evidence.

The chapters are systematic and well-described:

- Cover-ups and plots, such as those surrounding the Area 51 and Roswell incidents.

- UFO sightings; ranged from the well-known (such as the Phoenix Lights and the Ariel School Incident) to the obscure. 

- Alien abductions; such as the ones that happened to Betty and Barney Hill and in Pascagoula.

- Ancient aliens; such as the alien builders of the pyramids and Biblical astronauts.

- Reports from the government and military, including Project Blue Book and accounts of UFO sightings near nuclear weapons installations.

- Scientific proof, such as the interstellar 'Oumuamua object and the "Wow!" radio signal.

Even if it is obvious that we cannot draw a firm conclusion concerning UFOs from the reading, the book is entertaining and well worth reading.

It is informative, backed up by data, and a wonderful starting point for people who want to understand more about the UFO phenomenon.
