A serious look at how the Bible came to be causes atheism.
Decisions of groups of men made hundreds of years ago were enforced and there's the Bible. Decisions were based on politics, influence, popularity, what particular writings could do to help or harm the Church. As humans, we cannot even agree on recent history, so we will never agree on how the Bible came to be what it is.
If JW's really thought about it, they use the Protestant Bible without the Apocrypha, modified to their own doctrine, and instead of denying that, they pretend God had such a huge hand in making it so, despite the same people who brought them the NWT making a claim that they are not "inspired' or "infallible" but, somehow their warped translation of the Bible was guided by God.
