"The Bible describes a day as light to dark and to light again. At work so don't have the direct passage, but the Bible is clear on what a day and it is used in all forms of contexts. After 3 days, Jesus ascended into Heaven, Moses' flood was 40 days and nights, etc..... I don't believe there are any metaphors in Genesis, but that's my humble opinion."
The question is, what does the text itself say. The question is not, what do we want the text itself to say in light of our evolutionary presuppositions. If one just accepts the absolute authority of Scripture, and then reads the Genesis account, then it is fairly obvious that it was meant to be taken as "fact". It only becomes tricky when you approach the text with presuppositions not based on Scripture.
All that is to say, you are right. Genesis is not a metaphor. I'm pretty sure that Jesus, Paul or any of the NT writers didn't think so either.
Well said!
