The Babylonians give their gods a very "human" character. The Epic of Gligamesh, implies that Enlil was driven to wrath over a petty annoyance (i.e. noise). This is a very human thing to do. Why would a deity be incapable of blocking out the noise, or drowning it out with a loud noise of his own? Why did he have to "drown the whole world? It also reveals a very rural, and agrarian environment. The simile compares the "bellowing" of humanity to a "wild bull." The Audience and author both would have to hear the bellowing of a wild bull for the simile to have meaning.
