God the Father created the light from darkness.
I’ve seen it described in this way in Genesis 1:
1. light (day)/darkness (night) = 4. sun/moon
2. arrangement of water = 5. fish + birds from waters
3. a) dry land = 6. a) animals
b) vegetation b) human beings: male/female
God spoke in Genesis 1, the Word of God, being the Son of God. At the moment that God said “Let there be Light”, was the Son of God both fully human and fully God?
