It's not just that, Leo, it's also that the there are a lot of religious books, but it was decided that some *are* holy, and others are not. Which is just completely stupid. This page features some nice questions to Christians:
http://www.churchofreality.org/opinion/christian-reality.htm 
- Do you believe that the Bible is the word of God, that it has been accurately preserved through the ages, and that everything it says is true?
- There are thousands of denominations of Christians. Why do you believe that your denomination is the best one - if you believe that - and can it be improved?
- If you realized that a different denomination of Christianity were more accurate than the one you are currently a member of - would you change religions?
- Do you consider yourself to be one of the "chosen ones"?
- Do you really think that everyone else who isn't a Christian is really going to burn in Hell forever?
- Do you think that Armageddon will occur in your lifetime?
Also, I ask all Christians: Why doesn't God come out of hiding? I mean, in the bible it's very clear he can do all sorts of super-natural things.. If he would show up and do some of these super-natural things, for everyone to see, I would believe in God.
