Do UFOs really exist? Are we alone in the universe? Is the government hiding the truth from us? With his signature objective and balanced approach, J Allan Danelek explores the controversial questions surrounding extraterrestrials that have raged for years. This wide-ranging and captivating book begins with a historical overview of the decades-ling debate, followed by an incisive look at the case for and against extraterrestrial intelligence. Danelek presents scientific evidence supporting UFOs and other life-sustaining planets, examines hoaxes and raises practical objections based on radar findings and satellite observations. Next he delves into government conspiracies and cover-ups - including Roswell, alien visitation and alien technology. There is also intriguing speculation about the alien agenda - crop circles, alien abductions - and suggestions of possible scenarios, both benign and malevolent, for first contact with an alien race.
