If you like this kinda secret society conspiracy stuff look up "Illuminati", "Masons", "Freemasons", "P2", "David Ickes", "Reptilianoids" there's enough up on You Tube to keep you busy for years!
They do make it up for their own benefit, there have been conspiracies involving the masons for centuries. It sells books. Where would Dan Brown, Bob Larson, David Ickes, Texe Mars and all the rest be without all this? The Illuminati only existed for a short period in Bavaria in 1776 however there have been all sorts of elaborate ideas concocted involving all the groups above. Each conspiracy a bit wilder than the next.
Just don't take any of it too seriously or you'll wind up crazier than they are.
Take a look at the book "Everything is Under Control" by Robert Anton Wilson which is an encyclopedia that discloses all these groups actual histories and their finger ponting-counter parts. Of course the editor of Conspiracy Now magazine claimed RAW was a part of the Rockefeller Conspiracy, to which he replied "That's true, every week a truck pulls up with a load of Rockefeller gold and stashes it in my basement!"
