Then God said: "Let there be light," then the light happened. It was the light that became the direction of first day for earth. And that light might related with the Spirit of God which was above the surface of the waters of the earth because the earth was covered with water at all and there had not been land yet. There was the dark part which was not enlghtened by the light. So there was the border between the dark part and light part. It was the first day after in the beginning.
