I found this list of 10 Questions that it says every intelligent atheist should answer.
I disagree with the title, but I think they're interesting questions. I did NOT write them.
Here they are. You can do them one at a time like the 15 Day Atheist Challenge, all at once, not at all, skip some, etc.

1. Are you a moral relativist, or do you believe in absolute morality? In other words, do you believe that cultures, or even individuals, can define their own rules on what is moral and what is not, or do you believe that every action has one unique, absolute, and true moral assessment?
2. Is your trust in science based on faith or based on science?
3. Where does language, art, music, and religion come from?
4. Suppose, hypothetically, that you met with someone who knew nothing about you except your first name. And this person was able to accurately name deceased family members, dicuss in detail how they died, and describe intimate personal details about your relationship with these people (including people you aren’t consciously thinking about). How would you explain this?
5. Is absence of proof the proof of absence?
6. What does the atheist position offer people? How has it improved your life? Why will it improve others’ lives?
7. When you attempt to use logic to conclude facts about religion, are you starting at the conclusion (God is not real), or are you starting at true premises? Be honest. If you are starting at true premises, then what are they? And how are they true? Think about #5 when you answer.
8. If all Christians believed that the Bible was entirely allegorical, what would you argue in support of your position?
9. [If it even is] Why is it important to you that everyone is an atheist?
10. Do you believe in extra-terrestrials?
