At the dawn of history, Egypt knew a writing system.

At the dawn of history, Egypt knew a writing system consisting of multiple parallel and continuous symbols ***

Flinders has seen the collection and scheduling of his book symbols going back to different eras, some dating back to about 7,000 years BC.

Terry also compiled written symbols on it from about 25 archaeological sites in Asia Minor, Greece, Italy, Spain and other sites in Europe, all of which appeared in late times compared to the Egyptian civilization.

After studying the historical evidence, Flinders Petri reached the following results: -

*** All letters of the alphabet have been present and used in Egypt since the pre-dynastic era (more than 7 thousand years ago) and are thus precedent to the emergence of a language anywhere in the world

All the Egyptian alphabet were clearly present in the oldest hieratic writings dating back about 5 thousand years.

And the same ones of the ancient Egyptian alphabet are then spread throughout the world.
