Which ancient Babylonian epic includes a flood survivor named Utnapishtim?

The Epic of Gilgamesh includes a flood survivor named Utnapishtim.

In the flood story embedded in the Epic of Gilgamesh, Utnapishtim is warned by the god Ea to build a boat and preserve life during a catastrophic flood. He later tells Gilgamesh how he survived and received immortality from the gods.

The account is especially important in discussions of Noah’s Ark because it is an ancient flood narrative with several comparable motifs, including a divinely instructed vessel, preservation of living beings, and birds used to test whether the waters had receded.

Utnapishtim is not Noah under a different name. He belongs to Mesopotamian literature, while Noah belongs to the Hebrew Bible. The two stories are compared by historians of religion and ancient literature, but they remain distinct narratives with different characters and theological settings.
