According to anthropologists, religion arose in the Neolithic period, a time that began 12 thousand years ago when people abandoned the hunter-gatherer lifestyle and started settling down in communities. By the time of the ancient Egyptians, religion had reached a significant level of development. The spirits of the seeds and the weather had evolved into gods. In the end, the gods numbered more than a thousand; every god required a temple, and every temple needed a priest, or several of them. For the Christian god to reach its final form took an additional three hundred years. It was accomplished through the work of dozens of bishops who wrestled with the problem of how a god consisting of three persons could really be one entity.
