What was the light God created on Day 1? Daylight, obviously. The light of day. But we still don't have the sun. And here's where Johnston points out the modern assumption in our thinking: in ancient times they didn't make the connection between the sun and daylight, but apparently saw these as two separate light sources. After all, there is already daylight before the sun rises, and when the sun sets it is still light out for awhile. Apparently they never put two and two together that the sun was the source of daylight.
