1. It is certainly true that throughout history people believe false things (including religions).

2. People will kill and die for believing in false things (e.g. middle eastern suicide bombers) thus wouldn't that mean fighting and dying for a argument does not prove it's truthfulness or falslyhood.

3. Were you taught what you believe or did it come to you without being taught? If it was a universal truth you would not need to be taught it, but rather wouldn't it come to you through divine means.

4. Would you agree that there is a financial motive for you to be taught what you're taught? (Child commercials, Parents gain lifelong financial support)

5. If it is a universal truth, why don't I believe what you believe, and if God has spoken to you, why not to me?

6. Why are there so many religions if there is one God and one truth?

7. Why does the Bible contradict itself so much? If it is of divine origin shouldn't it be consistent?

8. Can you pick and choose? Which parts of the bible do you pick to avoid contradiction? And if you can, what does it really mean to be a christian?

9. Do you reject parts of the bible? If no, then shouldn't you kill me for my "blasphomist" beliefs?

10. Given all of this, isn't it possible that you're wrong?
