The Creation account is clearly a historical account with a chronological order of events, divided up into seven days. Day 1 began with the formation of the earth 4.528 bya according to the Word.
If it is edited, its so severely edited that its more of a rewrite. The Egyptian creation story had multiple gods and also is not historical like Genesis is. There were no days in the Egyptian story.
I can agree here: Chronicle - a factual written account of important or historical events in the order of their occurrence.
Yahweh is not mentioned until the “second” Creation account which is also chronological in what follows.
Gen 2:4 This is the history( toledoth) of the heavens and the earth when they were created, in the day that the Lord God made the earth and the heavens,…
Gen 5:1 This is the book of the genealogy( toledoth) of Adam…
Gen 6:9 This is the genealogy( toledoth) of Noah…
The waters are anything in a liquid state that has no form, is formless and will conform to whatever is holding it. The early earth was a like a molten soup before something solid, that is the earth’s crust forming a “dome” shape… So then the full sphere of the planet is the firmament (heaven). The darkness that was upon the face of it can represent “obscurity” in that you could not see through the liquid, it was not clear.
The waters below (magma) gathered together to push up on the land to make it appear. God did not push the waters aside, defying gravity like the parting of the Red Sea.
Don’t throw out the history with the theology, and vice versa.
