Oh. I thought you didn't respond. I'm behind...
What is your Scriptural reference for the conclusion that physical time didn't exist "then"?
Regarding poetic prose,
When poetic prose mentions a day, say in a poem, do you assume because it's poetic prose that it's not a day? Or maybe when science disagrees with it, then it's not a day.
Here's an example where "day" is figurative: "As it is written: "For your sake we face death all day long; we are considered as sheep to be slaughtered."
(Rom. 8:38). We also face death at night, and the next day, and the next.
"For the day is near, Even the day of the LORD is near; It will be a day of clouds, A time of doom for the nations." (Ezekiel 30:3)
Here we know it's figurative, because he goes on to define it as a "time".
Is it ever defined that way in Genesis?
Gen 1:5
"And there was evening and there was morning, one day."
Gen 1:8
And there was evening and there was morning, a second day.
Gen 1:13
And there was evening and there was morning, a third day.
Gen 1:19
And there was evening and there was morning, a fourth day.
Gen 1:23
And there was evening and there was morning, a fifth day.
Gen 1:31
And there was evening and there was morning, the sixth day.
It appears that God went out of His way to try to get across to us that it was a day. Faith in God and His Word sees it; faith in man's science doesn't.
There is God's Word (truth), and there is man's spin on the truth. Guess which one much of science falls into.
