Question: Gen. 1:1616And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. (Genesis 1:16). Why the “two great lights” mentioned in the fourth day’s work, seeing that the sun is really the center of our planetary system? and how could it have been dark (ver. 2) if the sun was then in existence?
Answer: The two “great lights” were constituted as they still are (not created then) in relation to the earth prepared for man, like the work of all the six days. The dense darkness that prevailed in the chaotic state which preceded these days easily accounts for the gloom, though the sun, moon and stars were already in existence since God created the heavens and the earth, which took place, it may be, ever so long before the great geologic ages previous to the Adamic race. Not that scripture is occupied with these material processes; but it leaves ample room before the first day in ver. 3.
