>> Even when one reads Genesis 1 and believes that it is God’s idea of a day at work (i.e. not 24 hours) there is nothing in the Bible that states that evolution could not have happened.<<
“and the morning and the evening was the first day”. They were approx. 24 hr days or the change in the earths rotation would have had to have been very drastic. If you don’t accept the 24hr day and try to extend the time you will end up with some rather severe problems.
First, days on Earth were not always 24 hours. How do the authors of the account in Genesis know that when these events occurred (after all, they were NOT a firsthand account) were 24 hour days or not?
Second, the Hebrew word that was translated as "day" in the story in Genesis itself has different meanings and there is disagreement over the interpretation.
