73:1.1 On a normal planet the arrival of the Material Son would ordinarily herald the approach of a great age of invention, material progress, and intellectual enlightenment. The post-Adamic era is the great scientific age of most worlds, but not so on Urantia. Though the planet was peopled by races physically fit, the tribes languished in the depths of savagery and moral stagnation.
73:1.2 Ten thousand years after the rebellion practically all the gains of the Prince's administration had been effaced; the races of the world were little better off than if this misguided Son had never come to Urantia. Only among the Nodites and the Amadonites was there persistence of the traditions of Dalamatia and the culture of the Planetary Prince.
73:1.3 The Nodites were the descendants of the rebel members of the Prince's staff, their name deriving from their first leader, Nod, onetime chairman of the Dalamatia commission on industry and trade. The Amadonites were the descendants of those Andonites who chose to remain loyal with Van and Amadon. "Amadonite" is more of a cultural and religious designation than a racial term; racially considered the Amadonites were essentially Andonites. "Nodite" is both a cultural and racial term, for the Nodites themselves constituted the eighth race of Urantia.
73:1.4 There existed a traditional enmity between the Nodites and the Amadonites. This feud was constantly coming to the surface whenever the offspring of these two groups would try to engage in some common enterprise. Even later, in the affairs of Eden, it was exceedingly difficult for them to work together in peace.
73:1.5 Shortly after the destruction of Dalamatia the followers of Nod became divided into three major groups. The central group remained in the immediate vicinity of their original home near the headwaters of the Persian Gulf. The eastern group migrated to the highland regions of Elam just east of the Euphrates valley. The western group was situated on the northeastern Syrian shores of the Mediterranean and in adjacent territory.
73:1.6 These Nodites had freely mated with the Sangik races and had left behind an able progeny. And some of the descendants of the rebellious Dalamatians subsequently joined Van and his loyal followers in the lands north of Mesopotamia. Here, in the vicinity of Lake Van and the southern Caspian Sea region, the Nodites mingled and mixed with the Amadonites, and they were numbered among the "mighty men of old."
73:1.7 Prior to the arrival of Adam and Eve these groups—Nodites and Amadonites—were the most advanced and cultured races on earth.
