Religion, Darwin, and Evolution
Why must some people take the Bible so... LITERALLY? It's obvious that the world was NOT created in six days, and the world was not created in 4004 BC (ref: King James Bible).
In fact, St. Augustine, VERY famous Christian about 400 AD, wrote a book called "True meanings of Book of Genesis", where he specifically stated that the Bible should not be taken as the literally truth, and Bible is NOT SCIENCE< but myth and allegory. Bible are a collection of lessons and messages from God, and some concepts can only be explained metaphorically, such as creation of space and time.
So why does some people insist that the Bible is the literally truth? That started in the Reformation. Basically, the reformation claims that the Bible, NOT the Pope, is the true leader of Christianity. Rather than having the Pope telling you what the Bible means, each reader of the Bible should be able to decide what the Bible meant to him- or herself.
