I personally own about 10 Bibles, but that says nothing about how I regard it. For me it is one of the foundations of western Christian culture, and that's why I believe familiarity with it is important. To not know the Bible is to not know where we came from culturally.
One of the original questions for Karl was how he knew that God had spoken the words attributed to him in Genesis, and he replied that it is history. But it is not history, for the very definition of historic periods, as opposed to prehistoric, is that written records were kept. Since Genesis wasn't written down until about the 6th century BC, the six days of Creation are a part of the prehistoric period.
Of course, that is just a picky, technical answer based upon using the proper definitions of words. Just because an event is prehistoric doesn't mean it didn't happen, but it *does* mean that the evidence cannot come from contemporary sources.
In the case of the events in chapters 1 and 2 of Genesis, indeed in much of Genesis, particularly Noah's flood, there is no evidence that the stories aren't mythic, and much evidence that they are scientifically not possible.
