Here's a fun topic (well, I hope it stays fun, anyway!):
How do you think it would be if we discovered or came into contact with intelligent extraterrestrial life, in regards to religion? If you're a faithful person, would it shake your faith? Or would you be able to integrate it into your beliefs with little or no problems?
What about the aliens themselves? Do you think they might have religion? What do you think their religion might be like (yes, let's speculate!)? Do you think they'd believe in one God or many, or believe in deities as we might understand them at all?
Personally, I already think there's life out there and think we've probably been "visited" throughout our history, so I have no problems with the idea of alien life, in regards to my religion. It never made any sense to me that we would be the only planet with intelligent life. I do not think that humans are so privileged. Plus, I believe that God would've revealed Himself to them in a way that they could comprehend, too. Maybe Jesus appeared to them as an alien - who knows? (I hope they didn't treat Him the same as we did, though!).
So I'm very open-minded about it and the question excites me.
