Imagine if The Bible was written (or really voted upon) in the 21st century. I'm 100% sure the stories would be completely different, and there would be science in it.
The bible was not written to be voted on, it was written as the word of God. As the word of God, it is the absolute truth. I can't pick what parts of it I want to accept, and throw out the rest. I must accept it all, and I happily do.
At the same time, I do realize that many parts of the Bible were written as parables, and not as a history. If God wanted a complete history of the world, and how we came to be, I bet it would be too long to finish reading in one lifetime.
When you look at the themes in the Bible, they are just as good today as when it was first written. Don't be greedy, don't steal, don't lust, don't envy, don't do perverted acts. All the negative emotions the Bible warns about have made people suffer.
Pope John Paul II wrote in one of his books that a grave sin people make is to believe they are smarter than God. We're not. John Paul II gave the example of Adam and Eve, and how they were given rules by God, and how they were happy. But they ate from the tree of knowledge, and because of that one act, they were given the new power to Judge. When humans try to rationalize acts against the rules God has given, it leads to more suffering. If Adam and Eve never would have committed that first sin, we would all be in heaven right now. We're paying for their sin.
