The word “day” can also mean “period of time”, or era in the Hebrew iirc. Of course there is also a passage in there that talks about it was dark and then light, the first day, which implies one revolution.
I am of the mind that the Creation story is just that - a story. Revealed to man in the terms they could understand at the time. And pretty amazing how close it matches up with our theories of today (”big bang” vs. riding around on a turtle’s back). (The first use of the word “light”, I wonder if it is trying to describe energy and matter - E=MC2).
If it was just made up, I think I would have created man first (because we are “most important”), and then figured out a place to live, things to eat, etc. afterwards.
I think I said that, kinda. Since we don't KNOW, we can only speculate and that is often dangerous.
So I like to think that God's "Time" is not necessarily "OUR Time," and that there are many things we are still "in the dark about."
I just figure when Mankind is mature enough, Information will abound, and all "things hidden" will be shown, and at that time, we will understand it.
Until then, I reserve the right to give God the Benefit of my doubt. He will tell us all when the Time is Right.
That's a massive amount of projection, but Genesis 1 is impressive on many accounts, starting with the word "beginning", recalling that a "steady state" theory of the universe was in vogue through the 1950's.
I also note, as I've stated on this forum before, that it has a naturalistic bent, in that God speaks or commands, but does not tinker - "the earth brought forth grass"
