I enjoy searching for deeper meanings throughout the bible but I'm confused with your methodology, you seem to have found some connections but have no message or know where it's pointing you.
I have been studying Gen 1 creation account for quite some time. What I have discovered is day 1 parallels day 4, day 2 parallels day 5, and day 3 parallels day 6. with the first three days God prepares, organizes, and separates, with the last three days he fills up what he prepared, for example, on day 3 land is separated from the waters, and day 6 land animals are created, the two parallel each other. This follows a chiastic pattern of 1- 2- 3- -1 -2 -3 but it doesn't stop there. day 7 can be paralleled with before day 1 (day 0?) that existed in chaos. Day 7 is everything day 0 is not, it is light, completion, order and rest whereas day 0 is darkness, unformed, disorder, and a general unrest. so the chiastic pattern expands and takes a more nested structure to A- 1- 2- 3- -1 -2 -3 -A. But it still goes deeper, the intro and ending also parallel each other like bookends to the account so the chiastic pattern gets larger, A- B- 1- 2- 3- -1 -2 -3 -A -B.
As I studied the text more I could see that the chaos before the light and the arrival of the light that starts a process ending in rest can be viewed as a salvation metaphor of Christ coming into the darkness, but not just a salvation metaphor but also points to the coming of Christ himself to bring light into darkness. so the text is prophetic to Christ's coming but it is also prophetic to other things like the restoration of all things.
When I look at it as a salvation metaphor I see the spirit hovering first (the spirit calls us), then light comes (Christ), then the waters are separated (baptism) then land emerges out of the water (new creation in Christ). Now there is the days of filling and I know it has meaning but I'm not quite sure what it is. the creation of celestial objects could be a references to the gifts of the HS or since the sun was created after the light then the sun is not the source but it is a body that holds the light and spreads it, this could be parralleled with the believer's tasked to spread the light inside of them but Christ is the source of the light. but I'm not quite sure, then day 5 has the water animals and birds and day 6 has man. somehow this points ahead and I'm sure, it progresses into multiplication and fruitfulness but also is connected to the first 3 days but I haven't figured it all out so there is some mystery in the text still.
But... I know where it's going and I know what agrees with the text and what doesn't. I have a framework of meaning to work with and the meaning that comes from it will agree with the framework and agrees with the bible at large. You're not there, I don't see a framework you're working with so there is nothing to keep it accountable or know which direction it is going to go. You have a sense of it being serious which is dangerous, you don't know what the meaning is you're now looking for something controversial without any structure. anything could fit if you force it and that seems to be where you're at. are you letting the text speak to you or is it just a mouthpiece for something else? are you trying to turn it into something it's not?
