In Sumerian epics, the story of Gilgamesh conveys profound messages about friendship, mortality, and the quest for wisdom. Gilgamesh's journey highlights the inevitability of death and the human struggle for meaning. His friendship with Enkidu emphasizes the importance of companionship and the impact of loss. As Gilgamesh seeks immortality, he learns that life is fleeting and that one's legacy is shaped through actions and relationships rather than eternal life. Ultimately, the epic teaches that embracing mortality can lead to a richer, more fulfilling existence.
