P894:2, 80:6.1 From the times of the terminal Andite migrations, culture declined in the Euphrates valley, and the immediate center of civilization shifted to the valley of the Nile. Egypt became the successor of Mesopotamia as the headquarters of the most advanced group on earth.
P894:3, 80:6.2 The Nile valley began to suffer from floods shortly before the Mesopotamian valleys but fared much better. This early setback was more than compensated by the continuing stream of Andite immigrants, so that the culture of Egypt, though really derived from the Euphrates region, seemed to forge ahead. But in 5000 B.C., during the flood period in Mesopotamia, there were seven distinct groups of human beings in Egypt; all of them, save one, came from Mesopotamia.
P894:4, 80:6.3 When the last exodus from the Euphrates valley occurred, Egypt was fortunate in gaining so many of the most skillful artists and artisans. These Andite artisans found themselves quite at home in that they were thoroughly familiar with river life, its floods, irrigations, and dry seasons. They enjoyed the sheltered position of the Nile valley; they were there much less subject to hostile raids and attacks than along the Euphrates. And they added greatly to the metalworking skill of the Egyptians. Here they worked iron ores coming from Mount Sinai instead of from the Black Sea regions.
P894:5, 80:6.4 The Egyptians very early assembled their municipal deities into an elaborate national system of gods. They developed an extensive theology and had an equally extensive but burdensome priesthood. Several different leaders sought to revive the remnants of the early religious teachings of the Sethites, but these endeavors were short-lived. The Andites built the first stone structures in Egypt. The first and most exquisite of the stone pyramids was erected by Imhotep, an Andite architectural genius, while serving as prime minister. Previous buildings had been constructed of brick, and while many stone structures had been erected in different parts of the world, this was the first in Egypt. But the art of building steadily declined from the days of this great architect.
P894:6, 80:6.5 This brilliant epoch of culture was cut short by internal warfare along the Nile, and the country was soon overrun, as Mesopotamia had been, by the inferior tribes from inhospitable Arabia and by the blacks from the south. As a result, social progress steadily declined for more than five hundred years.
