c. They displayed human emotions.
Anger- Utnapishtim tells Gilgamesh the story of a great flood exacted on the people of Shurrupak. Ea informs Utnapishtim of the coming flood and instructs him to build a great boat and to stock that boat with all the creatures of the land. It is important to note that when Utnapishtim asks Ea about why the flood is coming and about what he should tell the people of Shurrupak, Ea has no specific answer for him, stating only that Enlil is angry. This suggests that the wrath of the gods can also be incurred without any obvious insult or explanation.
Vengeful- When Gilgamesh rejects Ishtar’s advances, Ishtar immediately turns to her father, Anu, to send the Bull of Heaven to punish Gilgamesh. At first, Anu rejects Ishtar’s request but she threatens to raise the dead to devour the living. Anu is frightened by Ishtar’s threat and releases the Bull of Heaven to appease her.
Frustration- This can be found in Anu's actions of giving in to his daughter when she threatens him.
