God created light on the first day. Why did he create light on the fourth day? Did you make plants first, and then the sun and the moon?

At that time, the earth was full of turbid air. First there was light, then there was photosynthesis, and then it gradually became clear. I didn't see Chu Guang (the sun) until the fourth day. Without photosynthesis, there would be no oxygen on the earth and life would not survive. In addition, the earth is full of water, so it must be cooled down to form the present north and south. Only in this way can we cultivate land.

I hope you are satisfied with the answer.
