God made two great lights: the greater light to rule the day and the lesser light to rule the night. And He made the stars as well.
Moses wrote in a popular style so that common people could understand him without instruction, not as a natural philosopher measuring spheres and distances. Astronomy itself is useful and unfolds God's wisdom, and studious men are right to pursue it; but Moses had to speak to the learned and unlearned alike, and so he descended to the grosser method of instruction that fits his office as a teacher.
AI summary
Light was at first chaos, scattered and confused, but God collected it and made it into several luminaries, both glorious and serviceable. He is a God of order, not confusion, and as He is light, He is the Father of all lights, placing them in the firmament like candles on a golden candlestick to give light to all that dwell below.

Commenting on Genesis 1:14-19
Men worship these great lights as if they were lords and kings, but they are God's own creations, placed in heaven to serve mankind. The sun is reckoned a hundred thousand times bigger than the earth; the moon is called great not for its bulk but for its quality as a light, reflecting more light upon the earth than any body save the sun.
