Irish author Patrick Heron returned to the show to share "the last few pieces of the jigsaw puzzle" concerning the pyramids and Bible prophecy. The Great Pyramid has a number of stunning mathematical features and could not be replicated today. There is enough stone in it to build a 6 ft. wall that stretches from New York to Los Angeles, said Heron, who believes it is impossible that the Egyptians constructed the Great Pyramid.

Rather, he suggested that 5,500 years ago, the Nephilim, who were the "fallen angels" written about in Genesis, built the pyramids and other ancient structures. They were beautiful looking "spirit men," who appeared human but were not bound by the same laws of physics as mankind, he explained. They mated with Earth women during two periods, before the Great Flood and afterwards, he added.

Heron said the Nephilim never died, but were entombed in an "abyss" or netherworld. According to prophecy in the Book of Revelation, a spirit man or "star" comes down to Earth with the "keys" to the bottomless pit. He identified this being as the Antichrist, whom people will be deceived into thinking is the Messiah, but he'll actually lead the world into the prophesied Apocalypse.
