Researcher of ancient mysteries, Wayne Herschel shared his theory that modern day humans are descendants of ETs who came to Earth 10,000 years ago. Richard C. Hoagland of Enterprise Mission, appearing during the third hour, agreed with some of Herschel's concepts, but thought his timeline was off. He suggested that rather than the Egyptian pyramids being 10,000 years old that their foundations were actually created 200, 000 years ago, and the timing was associated with changes in human DNA development.
