Egyptian mythology [SEP] Origins
The development of Egyptian myth is difficult to trace. Egyptologists must make educated guesses about its earliest phases, based on written sources that appeared much later. One obvious influence on myth is the Egyptians' natural surroundings. Each day the sun rose and set, bringing light to the land and regulating human activity; each year the Nile flooded, renewing the fertility of the soil and allowing the highly productive farming that sustained Egyptian civilization. Thus the Egyptians saw water and the sun as symbols of life and thought of time as a series of natural cycles. This orderly pattern was at constant risk of disruption: unusually low floods resulted in famine, and high floods destroyed crops and buildings.
