billions of people can be mislead or wrong. The bible is not perfect, my one has a page missing. Your opinion is fine, though i think of the billions you claim to believe the bible is the book they will follow many haven't read it, or can't read; of those who have read it, not all believe it is perfect even if they agree with what it has to say on many issues; of those who do believe it is perfect not all agree on which revision to revere.
So not only do billions of people not follow the bible, (a majority, cause of the billions of Hindu, Islamic, buddhists, and atheists in the world) Also just because a majority believes something doesn't mean it is true - this doesn't prove the bible is imperfect, it doesn't prove anything.
@Fanas, as demonstrated your extreme views are as faulty as the opposite extreme.
regarding suffering: From an atheist's standpoint life only has meaning when humans create it, thus suffering and pain are meaningless as is everything else unless we choose to value them(which is easy enough due to brain chemistry, but we are actually just bio-machines which find it useful to create meaning in our lives because that makes it easier to make decision rather than being paralysed with options or suicidal from the idea that our actions are pointless)
What we value and how we treat each is something which religions the world over can teach us much about, though there are other non-religious philosophies which also have much to teach. Understanding more than one allows us to better appreciate our own religious beliefs and practices, and teaching only one prespective limits our awareness of any alternative options. (if you have no other options then you're not choosing to follow your own religion, and if it's not a choice which you are making, just a habit, or tradition then you don't really believe, you're just going through the motions - by the way, my education included religious teaching of the catholic persuasian as that is the standard in a religious Catholic country like Ireland, so i have an idea of what i'm talking about)
There is suffering because we don't live in a perfect world, which would be boring, and thus wouldn't have had the need to evolve inteligence. Any world in which you can ask the question must have intelligence, and therefore requires suffering. (if the physics was different, there would have been no benifit to developing intelligence, and the chances of a randomly assorted atoms coming together to form intelligence is incredibly unlikely, thus only by providing an evolutiontary advantage can intelligence exist. It is advantagous to avoid suffering - you can't build a free energy machine because that would completely unbalance the universe, it's a fundamental part of our universe.)
