I am shocked by the number of positive reviews of this book. People in this country must have extremly little background in science if they believe the thesis of this book. If anyone had done research on any of Hancock's claims, they would know that he makes entirely illogical and unscientific arguments. Future readers- don't waste your time with this pretend science.
