It's odd that the lighting supposedly went from absolute to relative on day 4 (creation of the Sun) with no mention of the change in how "evening" and "morning" work. Maybe the original light source after darkness was created could have been where the Sun ended up being.
It was not understood that it was the sun that made the day light at the time Genesis was written. Light just was, god created light on day one then divided it from the dark and called the light day and the dark night. The sun and moon were created on the fourth day as afterthoughts to rule the day and night that had already been created three days earlier by the understanding of Genesis' writers. According to those writer's understanding, the light of day still had nothing to do with the sun other than maybe to let the sun know when to come out.
I have no idea why they had not figured out that the sun was the source of light. Maybe it was as simple as they noticed that it was still light under a heavy tree canopy where the sun couldn't be seen so concluded that the light didn't come from the sun.
