You are not paying attention that since day, years, seasons and so forth did not happen until sometime during the fourth day, then days 1-4 could not have been 24 hours long because 24 hour days did not happen until sometime during the fourth day. And going by your logic of an evening and a morning on each day makes no sense because for the seventh day it does not say there was an evening and a morning a seventh day. Or the seventh day in ongoing yet.In Genesis 1 when the days are counted we see something interesting. The first day is cardinal ( one day), 2nd to the 7th day is ordinal.(second, third...day). It reads evening and morning one day. Moses under the inspiration of God Defined what a day is one evening one morning. Nothing in the narrative suggests that they are God's days,
Follow your logic and your high standard. If it doesn't say explicitly that they are God's days then it's not. If it says explicitly it's one day one evening one morning =24hr. Dat. then it's one day. Notice the duplicity and hypocrisy you practice.
How could you have had 24 hour days when there were no seasons from days 1-3 and only sometime during the fourth day did seasons occur? Read it carefully and it says that is when the greater one started ruling the day and the lesser one started ruling the night. Or so many hours of darkness and lightness only happened during the fourth day.
