Ok, so the Bible is supposed to be the book of "God" right?

But, who wrote the book? People, just like you and me.

You can argue and say "prophets" were told what to write in the Bible for others to read. How do we know they weren't just crazy, delusional schizophrenics and heard voices in their heads and thought it was "God" speaking to them?

And to those who say you hear "God" speaking to you, what does he say?
How do you know its "God" and not you being a schizo?
Why wouldn't "God" just write what he wanted to tell us in stone and let it persevere through the ages for all of mankind to see instead of letting just a few people tell us what he wants?

Just a few questions that came to thought.

Discuss.
