Well I’m not sure how much of a waste my time is on this thread, but the bible wasn't handed to Moses or anyone from the hand of God. Its book compiled of smaller books and letters, and yes by man. There are many different kinds of bibles, i.e. the bible put together by Jefferson says anything that he wanted it too. Anytime he didn't like what God had to say to him he just cut it out. But the basic editions, NIV, NASB, have set rules to them. If a book contains text that contradicts the rest of the bible, then it can't be apart of it. However, many people find many contradictory passages:

The first part; the Old Testament, contains a lot of the Jewish religion, while the last part; the New Testament, is Christianity. And being of two different natures they will contradict each other, like apple and oranges. However bloodyfart has a lot of wisdom on the third point. If the bible could have been proven correct it would have been done so along time ago, you're not going to find anything new on this message board, and unfortunately there are people who will believe in it no matter what and there are those who will not believe in it just as stubbornly. Do research on your own, don't depend on others to convince you of where you should stand.
I've heard that "Case for Christ" is a good book for the questions you have, but i have yet to totally get through it myself.
