I didn't say it was unimportant. Historically speaking, it's a tremendously important piece of work. But then again so is Mein Kampf. Importance doesn't always equate to an inherent positive value.
As for it being "wrong", well that in itself is a largely subjective claim but I would put it to you that the Bible endorses things which are decidedly not good. Slavery for instance. Ritual mutilation, the beating and even stoning to death of children come to mind as well. Incest under certain circumstances also comes up once or twice. Ick.
This is not to say there aren't some good points in the Bible too but as Christopher Hitchens points out in his lectures none of the good points in the book (aiding the sick, feeding the hungry, loving your neighbour, etc) require a religious construct or a god, whereas all of the bad points (sinning, pennance, going to hell, etc) do.
The reality of the Bible is simply this: It was not "written" by god, it was written by men. Lots of men, over a looooong ass period of time. It's a collection of quasi-historical anecdotes, philospohical ramblings and hebrew fairy-tales, lumped together, paired down and codified by the council of Nicea and declared sacrosanct. All other thoughts and writings were declared apocrypha and heretical and to even mention them in public could lead to imprisonment, torture and death (also interestingly enough, in public).
If that doesn't sound like the work of humans and humans alone I don't know what else could persuade you.
