22. The goddess Tiamat appears in another myth, but here was portrayed as an evil dragon which was defeated by a brave god. This victorious god then became "King of the Gods" and created many geological features. What was his name?
From Quiz Mesopotamian Mythology - The Creation and Beyond
Answer:
Marduk
This story is similar to one of Norse mythology, when the brothers Odin, Vili, and Ve kill the frost giant Ymir and use his carcass to create the Earth. Marduk kills the evil Tiamat, who had terrorised the other gods, and used her body to form the heaven and the Earth. Her skin was supposedly stretched above the sky as a barrier, which explained the droughts of Mesopotamia.
The story of Marduk's role in the creation of Earth is described in the Enuma Elish, but an alternative version of the myth credits the Earth's creation to his father, Enki. Enki is one of the most ancient Mesopotamian gods, and some believed him to have adorned the Earth with crops, mountains and metals. It is also believed that he created the two rivers which give Mesopotamia its name (literally "between two rivers") using his sperm. These rivers are the Tigris and the Euphrates.
