Your perception is your reality; if you believe the bible is real, it is real to you. But this may not be so to other people because their perceptions are their reality, and it's best to respect other people's realities. Personally, I'm atheist; believe in what you want just don't impose your beliefs on me, that's like trying to change the rotation of the earth.
to me, it is, but if you don't want to believe in it, that is completely fine with me
of course it exist, if you believe in God, then you believe in bible.
