1. What evidence do you have that a god (esp. your god) created earth? "Because the Bible says so" does not count. That's hearsay - and very old and unreliable hearsay at that.
2. What is heaven? Where is it located? How do you know this? Again, do not say, "Because the Bible says so."
3. How do you know Jesus existed? That he is Yahweh's son? That believing on him confers peace? Once again, do not say, "Because the Bible says so."
4. How do you know that there is an afterlife? How do you know that merely believing in Jesus will get me to that afterlife? For the fourth time, do not say, "Because the Bible says so."
5. Why do we all need to believe in something eternal or supernatural?
6. How do you know that Jesus is the "Truth" and what is "Truth" with a capital T?
If you can ever accept that the Bible alone is not a sufficient reason for believing these stories, then you'll be a step closer to understanding why we don't believe any of this at all.
If I were going to write a formal reply, it might look like this:
What evidence (other than a book of hearsay) can you bring to this court to meet your burden of proof?
The best answer I'd get is probably "personal experience" or a "personal relationship" with Jesus. That's all well and good but it won't stand up in court. Think about it.
