Has anyone here ever read the Law of One? Maybe this has already been stated, but, if you were to combine the information from that with Q and tidbits from other sources like (ugh) Tom Delonge, I think a painting of our past comes into view.
To put it very briefly, advanced beings offered early humans in Egypt information into how to obtain a sorta "universal intelligence." This was with the purposes of helping our race, but, ended with the priests and ruling class at that time using it as a way to gain power.
These few kept this knowledge a secret for thousands of years and that's what those in the Cabal have access to allowing them much greater insight than normal people. It might explain the pyramid on the dollar bill amongst other things.
Exactly what those techniques are, I'm not certain. Likely meditation based and/or sensory depravation. I recall reading that they would put initiates inside of a sarcophagus in the center of the pyramid. This sounds vaguely similar to Skull and Bones's practice of placing new members in a casket.
