Egypt is a greek name, just like heliopolis was really the city of On. The correct name is Kemet with means black land because of the soil of the nile. But since we all accept the name Egypt I will refer to it as such.
Mathematics, astrology, masonry and all the modern religions come from them.
The story of Moses never happened, for one Moses is a hebrew name not an egyptian one, so why would a child raised to be an egyptian prince be named in the language of the slaves. Moses was based on the story of an egytian priest named Thutmose, who later became a pharaoh after a war between Upper and Lower Egypt which were actually two different kingdoms at the time.
They had their own written language, but hieroglyphics were obviously used so events that transpired could be understood thousands of years later. There's been nothing found even suggesting that hebrews existed during this time or where slaves.
In fact the word Hebrew means wanderer, the were a nomadic tribe used as mercenaries by egypt, but that probably didn't happen until the ancient civilization had already passed.
The people in Kemet were negroids, some black as night, some reddish brown and so forth, hieroglyphics depict many different shades of people with negroid features. Some even say the original color of the negroids where green, because of the magnesium in the skin and some of the important figures in different dynasties are shown as such.
The statue of Seti which still stands today clearly depicts a black man.
People have to think how old kemet is, the glorious civilization that built these monuments pre-dates the so called events in the bible by thousands of years.
When the persians conquered Egypt it was no longer Kemet, those dynasties were long over, nobody can honestly say they know what happened to these people. Which is why their civilization remains a mystery to this day.
