Ambrose of Milan, on Gen 1:14

“And God said: Let there be lights made in the firmament of heaven, to divide the day and the night, and let them be for signs, and for seasons, and for days and years:”

“Look first on the firmament of heaven, which was made before the sun. Look first on the earth, which began to be visible and was already formed before the sun put in its appearance. Look at the plants of the earth, which preceded in time the light of the sun. The bramble preceded the sun. The blade of grass is older than the moon. Therefore, do not believe that object to be a god to which the gifts of God are seen to be preferred. Three days have passed. No one, meanwhile, has looked for the sun, yet the brilliance of light has been in evidence everywhere. For the day too has its light, which is itself the precursor of the sun.”
