The religion of Mesopotamia is considered to be polytheistic due to a belief in multiple gods. The most widely believed gods were considered to be Enki, the god of water, Enlil, the god of air, and Anu, the god of heaven. These gods were associated with aspects of nature. Each Mesopotamian city, such as Summaries or Babylonian, had their own gods and goddesses that they worshipped. Though, through all of religion, there had to be holy mediators that could talk to both deities and humans. Those middle men were named priests, and the power of which only was only challenged by the emperor of the city. This affected ordinary citizens and civilians by making them frequently look to the priests to gain favor from the gods. These civilians whole-heartedly believed that these gods can give salvation and blessings to the people, such as praying to Enki for having the ability to bless the city with rain and water. They prayed on a daily basis and put great faith in their actions resulting in good rain and blessings from the gods. Simply, their actions were guided by the hope of being rewarded by the gods for their good will, making them favorable.
