The role of religion in ancient civilizations was of primary importance. There was no idea of ​​a separation of church and state. Rather, religious and political authorities were inseparable, with political and royal authority seen as coming directly from the gods. Although various ancient civilizations had different religions and different interpretations of how these religions interacted with society, they all believed that the supernatural was a part of everyday life. Sometimes, as in the case of Ancient Egypt, rulers were considered real gods and venerated as such. Therefore, early law systems, such as Jewish laws regarding food preparation, were extensions of religious belief. This idea that the influence of the supernatural was present in everyday life was also shared by the Greeks. The ancient Greeks believed that gods inhabited the daily lives of mortals, often appearing as mortal humans or animals to interact with people. Likewise, the Sumerians believed in the daily impact of the gods on life, believed that the gods were vengeful and angry, and in the explanation of natural disasters. Ancient Rome also believed that the gods were present in everyday life, with some differences, as we will see later. In this essay I will examine how each of these civilizations' religions played a role in their societies. The Sumerians, unlike the Egyptians, believed that their leaders were of divine descent but did not believe that they were actual gods. The Sumerians believed that the natural world was composed of several gods: Nanna suen (God of the Moon), Utu (God of the Sun), Nin-khursaga (Goddess of the Earth), Enki (God of the Waters), and Enlil (God of the Air ) (Backman 2013, 16) . Natural events were attributed to the gods (Backman 2013, 16). If strong gusts arrived... in the center of the map... the Romans also liked it a lot. Marcus Aurelius, who ruled for just over twenty years, contributed to this school by writing a book in which he discussed the secrets of Stoicism. The book titled Meditations was “intended as a kind of personal guide or reflective exercise, the Meditations touching on morality, social care, and self-control, among other themes” (Backman and Axen 2014, 77). Both the Greeks and Romans considered themselves superior to other civilizations. This led them to attempt to spread to the rest of the world, this ambition and drive has undoubtedly contributed to the success of these civilizations. Works Cited Backman, Clifford R.
