Genesis 1:2 is the key to understanding the structure of Genesis 1. Genesis 1:2 states that the earth was “formless.” Day one then indicates the creation of day and night (Gen 1:3-5); day two describes the forming of the heavens by their emerging from the waters (Gen 1:6-8); and day three describes the forming of the earth by its emerging from the waters (Gen 1:10-13). Next Genesis 1:2 states that the earth was void. Day four indicates the filling of the heaven with sources of light: the sun, moon and stars (Gen 1:15-16). Their purpose was to rule the day and the night (Gen 1:16). On day five God created the birds and fish to fill the heavens and the waters (Gen 1:22). By implication they were also to rule the heavens and the waters. On day six first God created the animals to fill the earth and by analogy to rule it. (Gen 1:24-25). But the most significant part of filling the earth was the creation of man (Gen 1:26-27). “And God blessed them; and God said to them, ‘Be fruitful and multiply, and fill the earth, and subdue it; and rule over the fish of the sea and over the birds of the sky and over every living thing that moves on the earth.'” But in addition to stating the earth was formless and void, Genesis 1:2 also mentions that “darkness was over the surface of the deep and that the Spirit of God was moving over the surface of the waters.” Days one and five deal with the darkness problem. Days two and five deal with the deep by having the heavens emerge from it and days three and six deal with the earth which emerged “from the waters” (Gen 1:9).
