The Third Explanation, is clearly different from any other UFO book you might have readSpecifically, using peer reviewed known science, it details how aliens have altered the DNA molecules in early Hominins to genetically create Homo sapien sapiens - and possibly why?The first historical explanation of our origins was creation by an all-encompassing God. The second was the 'Darwinian Theory of Natural Selection' leading to speciation or species change. Noble's book records an amalgam of fascinating and accurate scientific evidence that identifies a never before scientifically examined THIRD explanation.To do so, it considers, who we are, exactly where we are, and whether many of the strange occurrences that humanity regularly records as having occurred in real space and real time (but are often ignored by the mainstream out of peer criticism and lack of knowledge) are part and parcel of a barely understood holographic universe.It looks at the Apollo astronauts and their outspoken views on Extra Earth Vehicles and examines some remarkable close encounters. It looks at the most advanced aircraft and the possibility of post gravity propulsion and considers many other advanced possibilities.It looks at the 9/11 conspiracy theories and reviews advanced hologram and cloaking technology ending with the remarkable assertion that aliens have left messages that well-known computer scientists and physicists are already examining.This book is easily understood because the most difficult subjects are made simple but accurately described. It is nevertheless a UFO book for thinkers not drinkers!
