I just want to point out that the Bible was first written for people at that time. Even though the Bible was declared to be the words of the all-knowing God, it would not explain facts like the science behind volcano erruptions, etc., because who at that time can understand it? If you read the Qu'ran (also called the Final Testament by Muslims, though I would not agree yet), it was written much later than the Bible and much more advanced in its scientific facts. For example, the Qu'ran pointed out that the Earth actually revolves around the Sun way before the European scientists.
