There is a problem with your explanation of why day is literal. Morning and evening have always meant "when the sun rises" and "when the sun sets." In Genesis the first few "days" occur prior to the existence of the sun. So how could there be a morning or evening?
I understand it this way.
When God instituted "day" (morning and evening), He invented a concept and declared that it was so. This means that nothing physical is required to validate His devices - there was morning and evening before the sun was in place. Neither does He need man to prove that it could be that way - God simply decided. Those who require God to have a sun first have a lesser god.
Had He done it the other way round, some would be able to say, "See? God required something physical to exist before using it". But He doesn't and He decided on the architecture and put the physical laws in place first. Then He formed the celestial bodies for our convenience and compelled the whole universe to comply with His design, showing that He is infinitely omnipotent. There is no end to His intelligence.
Besides, He divided the light from the darkness before He made the celestial bodies anyway. He, therefore, eliminates those who try to approach Him without faith which is another of His declarations. Heb 11:6KJV This is why naturalists cannot know Him; because He has decided they should not, but still be guilty of their self-inflicted blindness. 1 Cor 2:14KJV
