From The Urantia Book
(81:2.18) It was from these early huts that the subsequent idea of all sorts of basket weaving independently originated. Among one group the idea of making pottery arose from observing the effects of smearing these pole frameworks with moist clay. The practice of hardening pottery by baking was discovered when one of these clay-covered primitive huts accidentally burned. The arts of olden days were many times derived from the accidental occurrences attendant upon the daily life of early peoples. At least, this was almost wholly true of the evolutionary progress of mankind up to the coming of Adam.
(81:2.19) While pottery had been first introduced by the staff of the Prince about one-half million years ago, the making of clay vessels had practically ceased for over one hundred and fifty thousand years. Only the gulf coast pre-Sumerian Nodites continued to make clay vessels. The art of pottery making was revived during Adam’s time. The dissemination of this art was simultaneous with the extension of the desert areas of Africa, Arabia, and central Asia, and it spread in successive waves of improving technique from Mesopotamia out over the Eastern Hemisphere.
(81:2.20) These civilizations of the Andite age cannot always be traced by the stages of their pottery or other arts. The smooth course of human evolution was tremendously complicated by the regimes of both Dalamatia and Eden. It often occurs that the later vases and implements are inferior to the earlier products of the purer Andite peoples.
(79:1.2) For almost fifteen thousand years centers of mixed Andite culture persisted in the basin of the Tarim River in Sinkiang and to the south in the highland regions of Tibet, where the Andites and Andonites had extensively mingled. The Tarim valley was the easternmost outpost of the true Andite culture. Here they built their settlements and entered into trade relations with the progressive Chinese to the east and with the Andonites to the north. In those days the Tarim region was a fertile land; the rainfall was plentiful. To the east the Gobi was an open grassland where the herders were gradually turning to agriculture. This civilization perished when the rain winds shifted to the southeast, but in its day it rivaled Mesopotamia itself.
(79:1.8) But even in the twentieth century after Christ there are traces of Andite blood among the Turanian and Tibetan peoples, as is witnessed by the blond types occasionally found in these regions. The early Chinese annals record the presence of the red-haired nomads to the north of the peaceful settlements of the Yellow River, and there still remain paintings which faithfully record the presence of both the blond-Andite and the brunet-Mongolian types in the Tarim basin of long ago.
(79:6.5) Twenty thousand years ago the ancestors of the Chinese had built up a dozen strong centers of primitive culture and learning, especially along the Yellow River and the Yangtze. And now these centers began to be reinforced by the arrival of a steady stream of superior blended peoples from Sinkiang and Tibet. The migration from Tibet to the Yangtze valley was not so extensive as in the north, neither were the Tibetan centers so advanced as those of the Tarim basin. But both movements carried a certain amount of Andite blood eastward to the river settlements.

A 2014 article on foxnews.com reviews the discovery of pottery in souther China, dating back 20,000 years:
BEIJING – Pottery fragments found in a south China cave have been confirmed to be 20,000 years old, making them the oldest known pottery in the world, archaeologists say.
The findings, which will appear in the journal Science on Friday, add to recent efforts that have dated pottery piles in east Asia to more than 15,000 years ago, refuting conventional theories that the invention of pottery correlates to the period about 10,000 years ago when humans moved from being hunter-gathers to farmers.
The research by a team of Chinese and American scientists also pushes the emergence of pottery back to the last ice age, which might provide new explanations for the creation of pottery, said Gideon Shelach, chair of the Louis Frieberg Center for East Asian Studies at The Hebrew University in Israel.
“The focus of research has to change,” Shelach, who is not involved in the research project in China, said by telephone.
In an accompanying Science article, Shelach wrote that such research efforts “are fundamental for a better understanding of socio-economic change (25,000 to 19,000 years ago) and the development that led to the emergency of sedentary agricultural societies.”
