Here is a mystery,
Genesis1:3 Then God said, "Let there be light"; and there was light.
Gen 1:4 And God saw the light, that it was good; and God divided the light from the darkness.
Gen 1:5 God called the light Day, and the darkness He called Night. So the evening and the morning were the first day.
He continued to create on the second day and the third day, now on the fourth day He created the sun, moon and stars...
Gen 1:14 Then God said, "Let there be lights in the firmament of the heavens to divide the day from the night; and let them be for signs and seasons, and for days and years;
Gen 1:15 and let them be for lights in the firmament of the heavens to give light on the earth"; and it was so.
Gen 1:16 Then God made two great lights: the greater light to rule the day, and the lesser light to rule the night. He made the stars also.
Gen 1:17 God set them in the firmament of the heavens to give light on the earth,
Gen 1:18 and to rule over the day and over the night, and to divide the light from the darkness. And God saw that it was good.
Gen 1:19 So the evening and the morning were the fourth day.
now if the sun and moon where only created on the fourth day to rule over the day and over the night, and to divide the light from the darkness, what was it that God spoke on the first day when He said "Let there be light"?. what ruled the night and day for day 1, 2 & 3?...who says those first three days time spans where the same as the days that the sun and moon where created?...after all, God is not governed by time.
