And the Light that came from God was substituted by the sun as the thing that enlightened the earth. And it was happened in the fourth day after the beginning. And God also created other enlightening things in the space, which were called moon, and stars, to enlighten the earth in the daynight. And since then was automatically created the 24 hours per day based on the light of the sun and the earth rotation which had been started before the first day. See Joshua 10:12-14.
