What one has to understand is that the book of Genesis was first handed down verbally through the generations. Remember the "telephone" game when you were a kid? Furthermore, in the book of Deuteronomy it states that a day in the eyes of God is the same as 1000 years in the eyes of man. We're talking about primitive man who had next to no working knowledge of math. 1000 was used to signify a great many. So really, creation took 6 great manys (sp?). tl;dr - What if God created through the Big Bang (let there be light) so that we could evolve through intelligent design?
