I see nothing in your post which refutes (or even attempts to refute) the clear position in Exodus 20 that creation was six 24 hour days. You merely dance around the point. The context could not be clearer or more on point - relating a 24 hour sabbath to the 24 hour days of creation.
It’s a metaphor, not a geology lesson.
God had Peter put into writing how long a day with Him is. I have no authority to refute Peter but to read with understanding how not to be willingly ignorant. It really bothers me when God says some of His children are 'sottish' (sottish means stupid) (Jeremiah 4:22) and willingly ignorant and while ignorance is not the sin, staying that way sure is not going to better my standing.
Those children that were brought out of Egypt are like preschoolers that needed to be taught the basic concept of who, what, where, when, why, and even how. You must ignore what is written up to and long after Exodus 20 to claim that is the definitive standard of time measurement for how long the days of creation literally were.
