Your making it up as you go along and it is completely unscriptural.
Genesis 1:1 "In the beginning God created the heavens and the earth."
+
There, the stars exist there is light in the universe.
After the creation of the univers which include the earth and the stars that have brought light into the universe the bible now focuses on the earth and states that it is still covered in darkness.
Gen 1: 2 Now the earth was formless and desolate,
* and there was darkness upon the surface of the watery deep,
*+ and God’s active force
*+ was moving about over the surface of the waters.
+3
For life to exist on earth God must remove the darkness and let the already existing light shine on the earth, and so he declares "Let there be light".
Genesis 1: 3,4 And God said: “Let there be light.” Then there was light.
+4 After that God saw that the light was good, and God began to divide the light from the darkness.
5 God called the light Day, but the darkness he called Night.
+ And there was evening and there was morning, a first day.
After clearing away the darkness the light now shines onto the surface of the earth. God then divides the light into Day and Night.
This is what the bible really teaches as confirmed by the genesis text. What you state is nowhere found in scripture, you are simply giving an opinion, your making it up as you go along.
