A history unknown to mankind for 100,000 years

Modern man has invented nothing: everything has already been lived and experienced by ancestors whose knowledge far surpassed his own. For these men, spaceships, cosmic journeys, Hertzian waves, jet engines, solar ions, and atomic energy would not have been novelties. Simply put, the superior ancestors radiated the planet and deteriorated the human species. Only a scarce minority of "initiates" are aware of the "truth," which was almost lost in time.
