Genesis 1:16 is often cited as the point when God brought the heavenly bodies into existence because most English readers import the sense of "create" into the Hebrew word asah translated "made."
Look very carefully at days 1-3, and we see that sunlight was part of those days too.
But the lights in the sky did not become visible for signs and seasons until Day 4.
That was when the darkness of Job 38:9 was finally diffused enough to allow a [theoretical] earthbound observer to actually see the light sources rather than indirectly register refracted light through thick,
Also, please note that Day 1 starts in verse 3 with the divine fiat: "And God said...."
Most believers who have looked into the topic agree that each of the six creative-work days of the Genesis 1 record end with the same phrase. The pattern is obvious.
“there was evening and there was morning, day one.” [verse 5]
“there was evening and there was morning, day two.” [verse 8]
“there was evening and there was morning, day three.” [verse 13]
“there was evening and there was morning, day four.” [verse 19]
“there was evening and there was morning, day five.” [verse 23]
“there was evening and there was morning, day six.” [verse 31]
Do you know anyone who seriously disputes the validity of this pattern? Well, that’s how each of the six creative work days end. How about how the days start? Let’s reverse map this.
If day five ends in verse 23, let’s see how verse 24 starts the sixth day. Verse 24 reads: “And God said….”
If day four ends in verse 19, let’s see how verse 20 starts the fifth day. Verse 20 says: “And God said….”
If day three ends in verse 13, let’s see how verse 14 starts the fourth day. Verse 14 reads: “And God said….”
If day two ends in verse 8, let’s see how verse 9 starts the third day. Verse 9 says: “And God said….”
If day one ends in verse 5, let’s see how verse 6 starts the second day. Verse 6 reads: “And God said….”
So where do we see the start of the first day? Should we look for the phrase “And God said…” to see if it might just mark the start of the first day? Or should we cling to a status quo tradition because it’s what we are familiar and comfortable with?
Certain men want you to believe that the first day started with: “In the beginning….” My suggestion is that you read the text for yourself, and see if you can find the phrase “And God said…” somewhere after “In the beginning…” but before the end of the first day in verse 5.
