I was just thinking someing. The new testament could of been added to the bible in the exact same way the book of morman is. When jesus and such first came aorund they were the only ones to belienve un him and crap. Werll the mormon bible has all three books and how is it adcded? It is in mornom bibles to have all three books, after a while people began to expect both the new and old testament to ber in the bible? Well mabey it all started the same way the mormon bible didd. Sorry ig this is unreadavle I an a little bit dreunk.

Hmm, the new testament was written after the old testament? Jesus Christ, revelation. Perhaps there are people who do not believe in the New Testament and only the old. We need to get some PHDs on this right away.

Firstly there is no such thing as the 'mormon bible'.

The Latter Day Saints (to give them their correct name) recognise three works besides the bible as having scriptural authority. These being 'the Book Of Mormon', 'Doctrine and Covenants' and 'Pearl Of Great Price'.

We know from the NT that the first Xians devoted much of their time examining the OT for prophecies and references to Jesus. This OT (the LXX) would have been on scrolls or codex (primitive books). Over the centuries other books and the gospels were held by fairly common consensus to be 'canonical' and slowly codices were written with all the books in as a matter of convenience.

For example Codex Sinaiticus (from wiki)

Codex Sinaiticus (London, Brit. Libr., Add. 43725; Gregory-Aland nº א (Aleph) or 01) is a 4th century uncial manuscript of the Greek Bible, written between 330–350. While it originally contained the whole of both Testaments, only portions of the Greek Old Testament or Septuagint survive, along with a complete New Testament, the Epistle of Barnabas, and portions of The Shepherd of Hermas (suggesting that the latter two may have been considered part of Biblical canon by the editors of the codex

About 300 years after Jesus the Church more or less decided which books belonged in the bible (which is a horrible simplification on my part).
