Science fiction has had a heyday speculating on whether or not we are alone in the universe, but there are, in fact, real scientists trying to discover life on other worlds as we speak. What would it mean for our faith if they are successful? What would such life look like? 

On this week's episode, we ask Dr. Paul Rimmer, a Christian and geochemist at the University of Cambridge and the Leverhulme Centre for Life in the Universe, about his thoughts on the question. As someone who has actually participated in this research, what are the chances we will find life on other worlds in our lifetime? How ought the church respond? How would it impact your faith? Should we baptize a Martian?
