James Mixon, seems like you are only considering what people who believe in "Intelligent Design" (what a stretch!) and who are believes in the bible, consider, that is, what happened according to the bible God. However, as waton mention, and I'd like to add to, there's plenty of science that can trace a history of a lot of what happened (and formed) this wonderful planet we are in.
Remember that the bible was written at a time in humanity when humankind was the most naive about the world around it, so the explanations that they give are as good as the technology they had. Furthermore, for some reason people tend to forget that humans are as bad as they have been throughout their entire existence, hence, the same story tellers that we have today, we had back then.
The same way that we find people who tell stories, we did then.
