Okay, so moving on (or maybe moving back) to NAB Genesis 1 (and here I'll just quote the footnotes):
1, 1--2, 4a: This section introduces the whole Pentateuch. It shows how God brought an orderly universe out of primordial chaos.

In essence, chapters 1 through 2 (up to verse 4a) explains the creation or development of earth in the best way early Hebrews could describe it. If
you really look into it, they're right on target with modern science. Take a look at the footnotes that follow:
1, 2: The abyss: the primordial ocean according to the ancient Semitic cosmogany. After God's creative activity, part of this vast body forms the
salt-water seas (vv 9f); part of it is the fresh water under the earth (Ps 33, 7; Ez 31, 4), which wells forth on the earth as springs and fountains
(Gn 7, 11; 8, 2; Prv 3, 20). Part of it, "the upper water" (Ps 148, 4; Dn 3, 60), is held up by the dome of the sky (Gn 1, 6f) from which rain
descends on the earth (Gn 7, 11; 2 Kgs 7, 2. 19; Ps 104, 13). A mighty wind: literally, "a wind of God," or "a spirit of God"; cf Gn 8, 1.

The footnotes further explain Genesis 1, 5:
In ancient Israel a day was considered to begin at sunset. According to the highly artificial literary structure of Gn 1, 1--2, 41, God's creative
activity is divided into six days to teach the sacredness of the sabbath rest on the seventh day in the Israelite religion (Gn 2, 2f).

Hence the reason the sabbath always began in the evening. I'm sure you've all seen
Fiddler on the Roof and if you haven't, now would be a
good time to get acquainted with it.
Anyway, I think you get the idea of where I'm going with this. Anyone care to add or respond?
