How could there be light on the first day of Creation if the sun was not created until the fourth day?

God does not need the sun, moon, and stars to provide light. God is light! First John 1:5 declares, “This is the message we have heard from him and declare to you: God is light; in Him there is no darkness at all.” God Himself was the light for the first three days of Creation, just as He will be in the new heavens and new earth, “There will be no more night. They will not need the light of a lamp or the light of the sun, for the Lord God will give them light. And they will reign for ever and ever” (Revelation 22:5). Until He created the sun, moon, and stars, God miraculously provided light during the “day” and may have done so during the “night” as well (Genesis 1:14).

If the Aurora Borealis is made when storms on the sun form solar winds, or large streams of charged particles streaming toward the earth, then the northern lights in the photo above would not have existed on day one. What was the light?

I like the photo though, we saw this last February in Fairbanks, Alaska. It was 20 degrees below zero plus wind chill.
