If you read the first paragraph, you will see why:
quote:
Further, the first day may or may not have had a dawn. If the newly created light increased gradually like turning up a dimmer switch on a lamp in a room, then the first day arguably has a dawn. If there was just a brilliant flash, then the first day has no dawn. Days two and beyond certainly had a dawn since the text speaks of "morning". Granting that a "dawn" for the first day is an assumption, I will assume it until proven otherwise simply to make the first day symmetrical to all the others.

I don't think it's proven either way. You can have setting without morning. Just have the light flash into existence at zenith and then let it set. But, the POV is from one location on earth. There is no sequence of time for mornings and settings when viewed from space. But the text presupposed a sequence of time, so the Point of View must be one location on earth. Also no one ever confuses morning and setting at one place on earth with what is seen at the same time as another.
This remark is confusing. Did you really mean chapter 2,3,and up chapter 4?

Genesis 1:1 and it's history as given in Genesis 2:4-4:24 took place in that period of light that had become evening in Genesis 1:5.
