This does not say the (days or epochs) were separated by darkness and light (a 24hr day). In fact, the text says light=day and dark=night, and goes on to use morning/evening instead of day/night to describe the time periods.
Also, I said nothing about evolution. Why couldn’t have God prepared the universe/earth for billion/millions of years before he created man (as God lives outside of time) and the Bible still be literal and true? Evolutionist need to earth to be old for their theory to hold water, but creationists don’t need the earth to be young for their theory too.
I agree the Bible can be 100% true and some can have a wrong understanding of it. The bible and the creation both speak to the truth of God, so I consider both of them like His word to us.
So you discount the terms “day”, “night”, “morning”, “evening” as meaning something other than a day. That being the case, how should God have described a period of time that is a day?
