Were humans created, or did we evolve? MacKay offers a 3rd theory - that we are really extra terrestrials. "The Secrets of the 3rd Theory" takes the reader on an odyssey of human growth, regression and learning. Fanciful technology and charming characters share their journey from paradise to paradise. We are left with the question of whether humanity will treat Earth with respect and live to be part of the paradise Earth was meant to be, or whether Earth will return to paradise without us.
