The Bible not only tells us that God is light, but we are told that He caused natural light to exist upon the earth. However, in the beginning, light wasn't divided from darkness. There was no division of day and night. Atheism has no explanation as to why we have the amazing balance of the earth spinning as it moves through space--turning upon its own axis, and travelling around the sun at such a speed that we end up with the divisions of day and night.
Each year, our winters faithfully produce shorter cold days, and then we enjoy the warmer summer days. This consistently happens to a point where we can predict the average meantime temperature on a certain day or night of the year, 100 years ahead in time.
This is because there is an incredible balance within the division between day and night caused by the constant and predictable movement of the earth, as it flies at breakneck speed through space. The Bible says that it was God that created the light and caused the division. Again, atheism has no explanation. It was just a cosmic accident that happened. Day and night just are.
A committed atheist will tell you that it isn't ordered at all, it just looks like order.
He believes that there was a point in time billions of years ago when there was a semi-sunrise and semi-sunset, semi-light and semi-darkness, and a semi-day. He believes that it took time to bring about the order and completeness we think we see.
Instead of admitting that he has no idea how all this happened, he will mock you by saying that you are ignorant as to the difference between biology and cosmology.
