Why is monotheism more advanced than polytheism

not really. However, monotheism can unify ideology more than polytheism, which is equivalent to completing the process of vassal enfeoffment to centralization in religion. So it has its advantages.

A religion that believes that there is only one personality god and worships him. As opposed to polytheism. It is different from pantheism which believes that there is an impersonal god inside the world (including human beings themselves) and deism which believes that God is outside the world. It is generally believed that monotheism includes Judaism, Christianity and Islam. However, the concept of monotheism is also relative and constantly evolving, and no religion is absolute monotheism from beginning to end. Monotheists believe that the unique God they worship not only created the world and human beings, but also dominated the world and human beings with their wisdom and power. He is an omnipresent, omnipotent and omniscient spiritual entity, which transcends the world and exists in the world. Believers can approach him through prayer. Monotheism denies the existence of other gods, but it does not deny the existence of other spiritual bodies. There are various levels of angels and demons in the major monotheistic religions. Therefore, some scholars believe that these are traces of the Supreme God from the gods. Since the 19th century, it has been argued that religious ideas have developed from animism in primitive society to monotheism, and monotheism is the highest stage of human religious ideas. However, scholars such as Andre Langer and William Schmidt believe that monotheism exists among primitive peoples. This primitive monotheism or Protomonotheism theory holds that other forms of faith are differentiated and evolved from the original real religion, namely monotheism. Just as Judaism, Christianity and Islam all think, monotheism originated from the revelation of God to Adam, the ancestor of mankind, and then human beings gradually became polytheistic because of the fall of the ancestor. Islam believes that Christianity's doctrine of Trinity is a form of belief in three gods, while Christianity believes that there is no contradiction between its doctrine of Trinity and belief in one god. Others think that Sikhism, which combines the monotheistic concept of Islam with the polytheism of Hinduism, and Zoroastrianism, which belongs to dualistic religion, can also be regarded as monotheism in a sense because they only worship good gods. Engels pointed out: "Without a unified monarch, there will never be a unified god." Many people think that monotheism developed from polytheism and came into being with the emergence of classes and countries.
