For centuries civilization has evolved and spread across the globe, causing for many cultures, traditions, and especially religions to develop. Even in ancient societies such as Mesopotamia and ancient Egypt, religion was one of, if not, the most important aspect of an individual 's life. The religions found in Mesopotamia and ancient Egypt would shape how relationships within society functioned, including how communities related themselves to the divine and the role of leaders and priests. Furthermore, these religions would also affect how each of these societies thought about justice and even influenced attitudes toward the afterlife.
