What's Our true History?

They will never admit that there was a civilization that was older than a couple of 100,000 of years. And perhaps a lower civilized people have overthrown the old world and take the power of the old highly developed civilized world of last builders of this world.. But the new rulers could not understand everything that was already there. which caused much destruction. It is likely that some of what they could contain and use has been retained. To partly re-release it in a different casing, as if it were a new invention. . Something has happened, that's clear. Why does no one know where humans come from anymore? There is a "black out" in human history, consciously or unconsciously! Our entire history has been suppressed. Everything that falls outside our timeframe is vehemently denied by the leading Academic and Anthropologist clowns sociality.
