Genesis 1:2-5

2 Now the earth was formless and empty. Darkness was on the surface of the deep. God's Spirit was hovering over the surface of the waters.

3 God said, "Let there be light," and there was light.  4 God saw the light, and saw that it was good. God divided the light from the darkness.  5 God called the light Day, and the darkness he called Night. There was evening and there was morning, one day.
