(FTR, I believe in theistic evolution. I believe evolution happened, but that god helped it happen and also created the big bang. I believe that the 'six days' thing doesn't mean days in the usual sense but instead is a term used for a division of the time between scientific beginning of earth to the birth of Adam and Eve into six equal parts.)
I don't understand why more intelligent Christians don't think this way. You can believe in a literal bible AND evolution. Remember, a day is like a thousand years to God, and a thousand years is like a day. All the sh**t that happened before the flood could have taken billions of years and it wouldn't make the bible untrue. Evolution is real, denying it is like denying gravity. Humans can be "special" and still have evolved from something else.
