The problem with that is that not all of the Bible can be taken literally.
Also, some of the stories, such as the feeding of 5000 by a few fish and loaves of bread, are accounts written by humans, and thus can contain small contradictions. Think about it - if you and I and two others all experienced the same thing, then wrote about it days or years later, our stories would be different. We would remember things differently, and perhaps not entirely accurately. In the case of the feeding of 5000, one of the accounts of that story gives a different number, I think 3000 instead of 5000. To me, that just goes to prove the validity of the stories being real. If someone was trying to "make up" the Bible, you can bet they would try to get the stories accurate down to the last detail to make it as "truthful" as possible.
