It said in the bible that on the first Day God created the Heavens and the Earth and the earth was formless and darkness covered the deep waters. And the Spirt of God was hovering over the surface of the waters.Then God said let there be light and there was light. And God saw that the light was good. Then he separated the light from the darkness. God called the light day and the darkness night. ( Genesis 1:5). So know one knows how there actually created.
