I think what sends historians round the bend is the fact that people once evolved to an advanced state that wasnt technologically driven.

And yet it was always there running along side them.

Then a catastrophe occurred and after there was a dumbing down of the human psyche due to among other things intellect and warfare being chosen over our first given qualities.

Then once more, after some other more physical catastrophes; western humans once again de evolved slightly and lived in squalor in some places and started to believe in bullshit like the Earth being flat and that their century invented shipping first and went on discovery missions first.

(And the 'thinkers' bought it hook line and sinker).

Australians dug up timber ship remains on our ship wreck coast right here in Victoria from way way pre Sumerian times, that also recently rewrote our history. Fact.
