This is a well reasoned and scientifically researched look at UFOs and the possibility of extraterrestrial life elsewhere in the Cosmos.It also brings together both science and Christian Faith to look at the question in a well researched and thought out viewpoint without any major contradiction.The authors, all credentialed scientists with backgrounds in Physics, Astronomy, International Relations, Philosophy, Social Science and Theological Studies to pool their experience to write an up to date book on this potentially divisive subject.The authors cover every major question and category under the UFO question;The beginning of the UFO era, types of UFOs, Contactees, Abductees, Government cover-ups and conspiracies, UFO cults, and in no other book on the subject, RUFOs- residual UFOs those that remain as completely unexplained.They also focus on such scientific questions as; Evolution's possibilities, Life on other planets and the requirements for life to arise under entirely different circumstances, and Interstellar space travel.They also look at religious based ideas; the Bible and UFOs, and Nature and Super nature as well as the Interdimensional Hypothesis of UFO origins.The only major critique that comes to mind came from my wife,the book was released June 1 2002,she thought the book was more recent, but in a highly niche subject such as this , this is the most up to date book on this particular subject that I have heard of. This book covers scientifically and religiously every major category of the UFO question that has been with us for centuries.
