The Extratempestrial Model

In The Extratempestrial Model, Dr. Michael P. Masters posits that UFOs and "Aliens" are our future human descendants, coming back through time to visit and study their own hominin evolutionary past.

As a professor of anthropology, Masters uses an abductive approach to logically infer the best explanation. He examines well-documented abductee experiences in the context of this time travel model, and considers other theories put forth to elucidate this complex and mysterious phenomenon.
