Genesis 1:3-8

And then God announced, “Let there be light,” and light burst forth! And God saw the light as pleasing and beautiful; he used the light to dispel the darkness. God called the light “Day,” and the darkness “Night.” And so, evening gave way to morning—the first day. And God said, “Let there be a dome between the waters to separate the water above from the water below.” He made the dome and called it “Sky,” and separated the water above the dome from the water below the dome. Evening gave way to morning—day two.
