The pre-clan society period refers to the period from the beginning of humankind to about 15,000 years ago. The production level during this period was low, and the production tools were simple and crude. Primitive people relied on the power of the group to obtain ready-made food from nature. Such as plant fruits, roots, insects, lizards and other small animals, and later gradually also hunted larger animals. Due to the low level of productivity, everyone must engage in labor production in order to obtain the minimum daily necessities necessary for survival. Therefore, every child must learn labor knowledge and skills from the older generation from an early age. When adults men and women go out together to collect and capture animals, children follow the elders at the station to expel and care for small animals, and collect plants in nearby areas. In this process, the elderly impart the methods and skills of making and using tools, and the experience and knowledge of productive labor to children. At the same time, the children are also told about the habits and codes of conduct of group living. The characteristic of education in the pre-clan period is that all children receive education in common labor and life.

In ancient Greek legends, Zeus is the highest god and the father of the gods. He rules the entire world in heaven and on earth. He is called the "father of the gods and the king of all people". It is said that as early as Homer's time, Zeus was revered by the entire Greek world as the highest god and the leader of the gods on Mount Olympus. The troubadours of Homer's time began to describe the image of Zeus in words. Sculptors and painters also created statues of Zeus. In the Greek civilization and religion of the Homeric era and beyond, Zeus mainly has two aspects: on the one hand, as the god of heaven and weather, he embodies the relationship between natural forces and humans; on the other hand, as the god of the ruler of clan society and slave society, he embodies the relationship between humans and society. These two aspects are extremely closely linked and constitute an important part of the ancient Greeks' understanding and grasp of the world in a theological way. The rise and fall of the divine sea people of Zeus - the fusion of the two origins of ancient Greece and the two aspects of his divinity, eventually making him the most powerful male god in the entire Greek history. Among the Greek gods, Zeus is the only one who is omnipotent. His name appears in various religious festivals, becoming more and more abstract and spiritual. Among poets, playwrights, and philosophers, his name is often equated with "god", just as it is common for later Christians to say that "god" is "god".
