I actually have good, non-nihilistic answers for these questions:
1. Why won't God heal amputees?
A. Because God gave us scientific thought to deal with healing the sick, and we have not yet figured out how to completely regenerate a limb (other than reattaching it or getting implants)
2.Why are there so many starving people in our world?
A. Because the world's food supply is unbalanced and those particular countries do not have a lot of access to trade with countries with abundant resources.
3. Why does God demand the death of so many innocent people in the Bible?
A. Because the Bible is a written history of the Jewish people and the Jews believed submissively in the will of God, thus being reflected in their writings.
4. Why does the Bible contain so much anti-scientific nonsense?
A. Such as? If you're referring to Creation, all oral traditions have the world created by fantastic means, not by science, because science was a foreign concept to people in those days.
5. Why is God such a huge proponent of slavery in the Bible?
A. Like I said, the Bible is a book of Jewish history, and they happened to fall into slavery several times because they were easily conquered.
6. Why do bad things happen to good people?
A. Our actions are not inherently good or bad in themselves, and thus "bad" things (also a subjective concept) don't really have any bias.
7. Why didn't any of Jesus' miracles leave behind any evidence in the Bible?
A. What, like the wine or something? What sort of evidence was there to be left behind?
8. How do we explain the fact that Jesus has never appeared to you?
A. Because Jesus died over 2000 years ago and cannot physically appear to anyone.
9. Why would Jesus want you to eat his body and drink his blood?
A. It's symbolic, dumbass. Jews were thinkers in concrete imagery, so Jesus was appealing to this side by saying such things.
10. Why do Christians get divorced at the same rate as non-Christians?
A. Because humans are human no matter what damn cult they belong to.
I say all this being a strong believer in God (not in a traditional sense, though). I think the only thing more ridiculous than Christians rationalizing their beliefs are people who criticize it seriously with sarcastic remarks. They're no better, really.
