3 big questions for a Humanist:
1. If the universe wasn't created, how did it begin to exist?
2. If everything comes to nothing, how can our lives have meaning?
3. Are some things wrong regardless of human opinion?  If so, says who?

3 big questions for a Christian:
1. How do you know your relationship with an Invisible Being is not a delusion?
2. How is following God's plan for your life compatible with freedom and liberty?
3. Why would anyone give their life to God now for eternal life with God later?
