Gen 1:6-8 And God said, “Let there be an expanse in the midst of the waters, and let it separate the waters from the waters.” And God made the expanse and separated the waters that were under the expanse from the waters that were above the expanse. And it was so. And God called the expanse Heaven. And there was evening and there was morning, the second day.
The word that is translated here as expanse is also translated as firmament or dome . The Hebrew word is raqia . Here’s a very good article from the BioLogos archives:
The Firmament is solid but that’s not the point

What you are trying to do is called concordism – but that has never worked. It’s like pounding a square peg into a round hole.

From the modern science (mind you that I am not the expert here and I only borrow mostly from the writing of Michael G Straus), it was the time when the atmosphere became translucent, so what was happening in the cloud became observable since the light now could penetrate though not fully. we had to wait till the atmosphere became transparent before sun and moon became observable.
No, this is not modern science. Besides, how did anything grow before the sun became observable by humans?
