Genesis 1:3-8

Then God said, “Let there be light,” and there was light. God saw that the light was good, so he divided the light from the darkness. God named the light “day” and the darkness “night.” Evening passed, and morning came. This was the first day. Then God said, “Let there be something to divide the water in two.” So God made the air and placed some of the water above the air and some below it. God named the air “sky.” Evening passed, and morning came. This was the second day.
