That's not true. The Mesopotamian, Greek, Kurgan, Indus and Chinese civilizations all started around the same time as the Egyptian one, if not earlier.
It could be argued that the Western European Megalithic civilization also started earlier than the Egyptian one as some megaliths are older than the first pyramids. The oldest megaliths are 7000 years old. The Predynastic Period of ancient Egypt started 5000 years ago.
It all depends on what you call "civilization". Is a primitive Neolithic agricultural society without cities and without a state a civilization ? I don't think so.
the egyptien civilization was exist before the discovery of writing
and if we tlak about the civilization Prehistoric you will see the badery and fayome civilizations
now egyptologist say that egyptiens discovered the Agriculture 12500 B.c
and when egypt unified in the first time about 4400B.c egypt was reached along way with civilization
Now we are in the year 6227 in the egyptien years and that`s means that ancient eyptiens discovered the Solar calendar 6227 years ago
and to discover that you need too much knowldage and that`s means the the civiliaztion was earlier .
all the europien civilizations were mainly taked from greece and everybody know that greeks get it from Egypt
there was american writer called martine palner who said that all the greece civilization is pharaonic and half of the language is egyptien
do you know that the world desert in egyptien mean the red land or the yello land and we said it "deshert" that`s for example
also you can read Legacy of Egypt to w. dawson to know how much the greece took from us
and for sur you red the book
