okay it's has been a while since I started a good old discussion about the bible. I will discuss a few facts about it that a lot of religions (including the WTBTS) don't like talking about.
First the formation of the OT. This information is from Richard Carrier historian and philosopher.
The Torah had already been canonized in some form possibly as early as 622 B.C.E. (when the true Torah was "discovered" and ceremoniously declared official by King Josiah, according to the Bible itself), though it was most likely significantly edited after the Babylonian Exile in the time of Ezra c. 500 B.C.E. The surest decision was made in the 2nd century B.C.E. when the Septuagint, an "official" Greek translation, was made of it by a council of seventy Jewish scholars in Alexandria.
This is only the canonization of the OT, the oldest manuscript that we have today dates back to the 3rd-2nd century B.C.( dead sea scrolls) and almost all of the modern bibles (including the NWT) do not use the dead sea scrolls as a reference.They use the Masoretic texts that dates back to the middle ages (9th century AD) or the Septuagint. (3rd-2nd century B.C.) All of these manuscripts have difference between them and there is no original copies of the OT so the claim that the first books of the OT were composed in 1513 B.C. by Moses is pure speculation with no proof. The claim that the texts we have today are almost identical to the original is more then speculation, it is just not true.
I will start with this. I await your comments.
