Genesis 1:1-5

When God began to create the heavens and the earth, the earth was complete chaos, and darkness covered the face of the deep, while a wind from God swept over the face of the waters.Then God said, “Let there be light,” and there was light. And God saw that the light was good, and God separated the light from the darkness. God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day
