The Osirion Civilisation is a term recently concocted to describe the peoples of the antediluvian Mediterranean region including pre-dynastic Egypt. The Osirion at Abydos is offered as an example of their architecture. The concept has been promoted by David Hatcher Childress in one of his books in the ‘Lost Cities’ series. Inevitably, the internet has taken up this highly speculative idea.
A 2021 video clip(a) presented by Jimmy Corsetti offers evidence that the Osirion was built 7,000 years ago allegedly by a civilisation that not only flourished before pharaonic Egypt but was global in extent!
