Apologist Mike Licona: “What turns you off about Christianity? Irrespective of one's worldview, many experience periods of doubt. Do you ever doubt your atheism and, if so, what is it about theism or Christianity that is most troubling to your atheism?”

Scholar William Lane Craig: “What's the real reason you don't believe in God? How and when do you lose your faith in God?”

Author and pastor John Ortberg: “How can you create a meaningful life in a meaningless universe?”

Resurrection expert Gary Habermas: “Utilizing each of the historical facts conceded by virtually all contemporary scholars, please produce a comprehensive natural explanation of Jesus' resurrection that makes better sense than the event itself.”

These historical facts are: (1) Jesus was killed by crucifixion; (2) Jesus' disciples believed that he rose and appeared to them; (3) The conversion of the church persecutor Saul; (4) the conversion of the skeptic James, Jesus' half-brother; (5) The empty tomb of Jesus. These “minimal facts” are strongly evidenced and are regarded as historical by the vast majority of scholars, including skeptics, who have written about the resurrection in French, German, and English since 1975. While the fifth fact doesn't enjoy quite the same universal consensus, nevertheless it is conceded by 75 percent of these scholars and is well supported by the historical data if assessed without preconceptions.

Philosopher Paul Copan: “Given the commonly recognized and scientifically supported belief that the universe (all matter, energy, space, time) began to exist a finite time ago and that the universe is remarkably finely tuned for life, does this not (strongly) suggest that the universe is ontologically haunted and that this fact should require further exploration, given the metaphysically staggering implications?

“And, second, granted that the major objection to belief in God is the problem of evil, does the concept of evil itself not suggest a standard of goodness or a design plan from which things deviate, so that if things ought to be a certain way (rather than just happening to be the way they are in nature), don't such ‘injustices' or ‘evils' seem to suggest a moral/design plan independent of nature?”

Radio host Frank Pastore: “Please explain how something can come from nothing, how life can come from death, how mind can come from brain, and how our moral senses developed from an amoral source.”

Apologist Greg Koukl: “Why is something here rather than nothing here? Clearly, the physical universe is not eternal (Second Law of Thermodynamics, Big Bang cosmology). Either everything came from something outside the material universe, or everything came from nothing (Law of Excluded Middle). Which of those two is the most reasonable alternative? As an atheist, you seem to have opted for the latter. Why?”
