IF THE SUN WAS CREATED ON DAY 4, WHAT IS THE LIGHT ON DAY 1?

The Bible stated in the book of Genesis chapter 1 that on the first day God said, "Let there be light and there was light". Yet in verse 16, the Bible stated that in day 4, God made two great lights which we have come to know as the sun and the moon. The question is, "if the sun was created on day 4, what is the light on day 1?"

(Genesis 1:3-5 KJV) And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

(Genesis 1:14-15 KJV) And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.

(Genesis 1:16 KJV) And 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.

(Genesis 1:17-19 KJV) And God set them in the firmament of the heaven to give light upon the earth, 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. And the evening and the morning were the fourth day.

To answer the question, you need to understand that the account of Genesis chapter 1 from verse 3 is about the re-creation (i.e. restoration) of the earth. Only verse 1 stated about the original creation. Verse 2 is about the state of the earth after some sort of judgment. From verse 3 is the restoration. During the judgment, the sun was caused to cease to give its light to the earth. This is similar to the judgement in Isaiah 13:10:

(Isaiah 13:10 KJV) For the stars of heaven and the constellations thereof shall not give their light: the sun shall be darkened in his going forth, and the moon shall not cause her light to shine.

But when the restoration started in verse 3, God commanded the sun to give its light in day 1. He said, "Let there be light and there was light". He did not create the light (sun) in day 1. He had earlier created it in verse 1 before the earth was destroyed and became formless and void in verse 2.

On the fourth day (i.e. from verse 14 to 19) , God made the sun and the moon to become visible from the surface of the earth. He made visual observation of the sun, moon and stars possible. During the judgment earlier mentioned above, the earth's cloud cover did not permit an observer on earth's surface to see these heavenly bodies (luminaries). More so, the orbits of these luminaries were apparently erratic during this judgement. However, on this fourth day of restoration, God fixed the orbits of the luminaries and diminished the cloud cover so that clear days would be possible, and thus heavenly bodies could be used to keep track of time just as He created them in the beginning prior to the judgement that caused the earth to be in darkness.
