Final answer:
The title of the best-known creation story from Mesopotamia is the Enuma Elish, not to be confused with the Epic of Gilgamesh, which is the earliest surviving work of literature but not a creation story.
Step-by-step explanation:
The best-known creation story from Mesopotamia is referred to as the Enuma Elish. However, the Epic of Gilgamesh is often mistakenly thought to be a creation story due to its prominence and early appearance in literature. The Enuma Elish is a different text entirely, focusing on the cosmogony and theogony of the Mesopotamian pantheon. On the other hand, the Epic of Gilgamesh is the earliest surviving work of literature, chronicling the adventures of the semi-divine King Gilgamesh of Uruk and his friend Enkidu as they engage in heroic deeds, confront their mortality, and seek the meaning of life. Thus, the correct answer to the question is A) Enuma Elish.
