Let The Creatard Shitting of Bricks Begineth

[Tonus]

On creation Day 4, the sun, moon, and stars became distinctly visible on the earth’s surface for the first time. The earth’s sky prior to day 4 would have had a heavy overcast appearance (but translucent) of carbon dioxide and water vapor. Plant growth increasing consumption of this carbon dioxide & water vapor resulted in the atmospheric transformation from translucent (had allowed electromagnetic non-visible sunlight spectrum to reach the earth’s surface to provide energy for photosynthesis) to a transparent atmosphere. Light created before Day 4, visible on earth on day 4. Again, after the first verse 'In the Beginning....' the frame of reference changes from the cosmos, to the earth for all references to 'days'.

That's not what it says.  On the first day god flips on the lights and "separates" light from darkness, which sounds like just the kind of thing an ignorant stone-age man might dream up about how we got day and night.  On the fourth day he creates two distinct lights to help mark the passage of time and to provide strong light during the day and a weaker light during the night.  As might be expected of a primitive culture, the assumption was that both the sun and moon were emitting their own light, and that this was somehow separate from the light of "day."  This primitive culture also believed that the sky was stretched over the flat world like a canopy (or a "vault"or "firmament").

And do realize that you are trying to explain how progressive growth caused changes to the environment as part of the same story that keeps telling us that god just spoke things into existence.  There is no reason to think that this magic wizard had to wait for the atmosphere to be properly balanced before he waved his wand and made the waters and sky "teem with living creatures."  It doesn't salvage the issue with the "lights" and simply makes it clear that you're grasping at straws to come up with explanations that you can wedge into the narrative.
