The legendary pre-flood civilizations like Atlantis, Thule, and Hyperborea were said to have been built on highly advanced science and technology, with a possibly direct connection with what is happening now around the world. In the pre-Flood world of Noah, it is written that there was cross-species (interracial) breeding going on between the “sons of God,” or the B’nai Elohim and mortal human women. The ancient rabbinic scholars believed that the term “sons of God” specifically referred to fallen angels and this was in fact the teaching of the early church for several hundred years.
The offspring of these fallen angels procreating with human women where called the Nephilim. Much of these stories have been effectively suppressed for centuries and banned from inclusion in later versions of the Bible, but have been recently re-discovered; for example in passages from The Book of Enoch. There are numerous other universal mythologies of pre-Flood legends that speak of these god men coming from the stars, or below the earth, and seeding human civilizations.
One of the forces supposedly used by certain groups in these pre-Flood times was a mysterious life energy, that the Nazis re-discovered, called the Vril force. The Vril force, the energy fields studied by Nicola Tesla, and what is now called scalar technology are based on similar theories deriving from quantum mechanics. The Nazi concept of a Vril force is based on the idea that a race of god men came from the stars in ships powered by this force and settled on the legendary island of Thule where they founded the civilization called Hyperborea.
