In creation myths, the primordial waters are often represented as originally having filled the entire universe, being the first source of the gods cosmos with the act of creation corresponding to the establishment of an inhabitable space separate from the enveloping waters.
In the first creation story in the Bible, there is only earth and water in a disorganized state: "Now the earth was unformed and void, and darkness was upon the face of the deep; and the spirit of God hovered over the face of the waters." (...). (Genesis 1:2.) The world is also created as a space inside of the water, and is hence surrounded of it, "And God saith, `Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.' " (Genesis 1:6).
