Bah. I hardly concern myself with whether in certain instances the term "day" meant a general period of time or twenty-four hours exactly... just like I don't believe that the "Lamb of God" could have been sheared for wool.
But consider...
1:11 Grasses and herbs are created - day 3
1:16 The sun is created - day 4
1:21 Sea creatures and birds created - day 5
1:24 Land animals and man created - day 6
Plants before the possibility of photosynthesis? There's no way that evolution would allow that ordering. Flying animals before land animals? We're supposed to believe that land-roming reptiles came between fish and birds.
It would be hard to argue that even the order of creation wasn't meant to be taken literally. There was no moral to that part of the story...
If "day" (the Hebrew "yom") must always be translated as a single 24 hour period,
No one claims that yom must always be translated as a literal 24 hour period. That's what I like about these evos: manufacture evidence for evolution; manufacture evidence against creation. Getting at the truth is not the objective.
