The Secret Societies have been present in the history of man for a very long time. It all started thousands of years ago with the "Brotherhood of the Snake", a secret society set up by an alien named Ea or Enki. This story is very carefully told in the Sumerian scriptures, which go back at least 6000 years. There it says man was created by draconian aliens, who came to this planet to exploit its resources - especially gold. But the work was heavy, so the alien race wanted someone else to do the hard work. Thus Ea, who was a brilliant scientist, created homo sapiens as a hybrid between a primitive earth life-form and the alien race.

It is value reading those texts as mysteries. Trying to work out what the real motivation was and how they aimed to extend their power.
The Aliens were here millions of years ago. The unexplained mysteries from the past including the foot prints, the porcelain "spark plug", the balls from South Africa etc.
They have worked out how the pyramids were built, so aliens weren't needed in that era. There is evidence from many time periods though.
They wouldn't regard the way we have stuffed up the planet as a sign of our being very intelligent.
