Hi Byrd,

There are those who believe the Egyptian culture originated in Indus Valley (the land of Punt to the West of Egypt) such as Dr. Adolf Erman (1854-1937) author of Life in ancient Egypt and A handbook of Egyptian Religion, "says that the persons who were responsible for a highly developed Egyptian civilization were from Punt, an Asiatic country, a description of which is unveiled by this scholar from the old legends - a distant country washed by the great seas, full of valleys, incense, balsum, precious metals and stones; rich in animals, cheetahs, panthers, dog-headed apes and long tailed monkeys, winged creatures with strange feathers to fly up to the boughs of wonderful trees, especially the incense tree and the coconut trees."
"Dr. Erman further says that analyzing the Egyptian legends makes it clear that from Punt the heavenly beings headed by Amen, Horus and Hather, passed into the Nile valley...To this same country belongs that idol of Bes, the ancient figure of the deity in the Land of Punt"

Louis Jacolliot has written:
“Egypt received from India, by Manes or Manu, its social institutions and laws, which resulted in division of the people into four castes, and placing the priest in the first rank; in the second, kings; then traders and artisans; and last in the social scale, the proletaire – the menial almost a slave.”

These statements would naturally leads one to believe social definition must predate the Egyptian culture, possibly as far back as Indus Civilization days, circa 5500 BCE-4000 BCE. If social definition had been conveyed to the developing culture of Egypt from another culture subsequent to that date, it surely would have influence development, because the Egyptians would have incorporated such important information into their society of calendar maintenance and land assessment.
