One of the “difficulties” found in the first chapter of Genesis is the mention of light existing before the creation of the sun. Here we explore the exegetical evidence of such claim.
On the first day we are told that God created light.
God called the light Day, and the darkness He called Night. So the evening and the morning were the first day. – Genesis 1:5
The sun was not created until the 4th day.
Let there be lights in the expanse of the heavens to divide the day from the night; and let them be for signs and seasons, and for days and years – Genesis 1:14
The light element has been created in Day 1. Day 4 is a matter of placing that element into a medium or object for illumination and for showing signs and seasons.
Imagine if there was no light emitting or reflecting from the sun, moon and stars, how would astronomy work? How would the Jews know when to celebrate Rosh Hashanah? How would our body know when to sleep and stay awake? See “Scientific Evidence For Biological Clocks & God” to find out how the sun affects our circadian clocks.
