No one knows. No one knows much about the origin, actually. But personally, I don't believe it xD Ask your religious leader, if you want a lame bullshit answer. 'cuz they don't know either.

Fact: The bible is a collection of other books, all of these books are ancient scripts. Fact: It is about 1800 years old (give or take ofc) Fact: The nice people at the Vatican carefully chose what to include and not to include. Fact: The bible you see today bears almost no resemblance to the original works. Fact: Jesus (IF he existed) and god have absolutely NOTHING to do with the writing of the bible.

Are you really seeking an answer? Or are you just seeking to mock those who believe? The Bible is a record of a long and ongoing conversation between God and mankind. If you read the whole thing in chronological order, you can see a remarkable congruence and coherence to it that wouldn't be present through the multiple authors and thousands of years if it wasn't. As it is commonly presented, with the books in the order in which they were translated, sometimes it seems jumbled, but if you ever read a chronological Bible, you can see that the same threads are coherently pursued from one end of the Bible to the other. Questions are raised in one book, and answered hundreds of years later through a different author. Prophecies are made in one book to one prophet and answered hundreds of years later. Sometimes God tells a prophet that Israel will be destroyed by a particular nation and a particular ruler and even gives the name of the ruler and the location of the nation and neither exist yet. But hundreds of years later, a man by that name from that location destroys Israel. We know that someone didn't just make up a story and write it down all at one time because there are existing copies from different eras all through history. The archaeological record has also been bearing out small details scattered throughout the Bible: the kind of details you don't find in fiction. It has the names of people and places right. The price of a slave 1800 years before Christ is correct. Small details of buildings are correct. The first five books are attributed to Moses. Some were written by the Kings, David and Solomon. Others were written by major and minor prophets. Some were dictated to a scribe. Literacy was not common then. Papyrus, parchment and other writing materials were scarce and expensive. Even hundreds of years after Christ this was true. Archaeologist recently recovered a scrap of the works of Archimedes, I believe, that had been reused to write a fragment of the Bible. That scrap of parchment was ancient, but they still reused it because it was worth more to them that the writing on it. The New Testament was written partly by Apostles and partly by other followers of Jesus. Mark was supposedly the son of the owner of the upper room where Jesus served the last supper. Luke was Paul's physician. Many of the epistles were written by Paul or other disciples. Some of Paul's letters predate the gospels and were written within 3 - 5 years of Jesus cruxifiction.

Blackberry, Others have already answered this but I wanted to share this with ya. I know that God is SO good, that if everyone on earth was totally wiped out except save a few people, God would have them write the Bible all over again. And it would be the same principles, because they never, never, never change. Take comfort in that!
