Space is a bit of a problem for religion. Most of the world’s major faiths started thousands of years ago, when we still thought the whole universe revolved around our planet, and now that we know that isn’t true, things are getting a little sticky for theologians.
Life might be out there, beyond the stars, and that changes things. After all, if God and His prophets came to enlighten life on Earth, what in the world happened on Kepler-186f? And what if all those crazy stories about UFOs are true? If there are life-forms out there that are smarter than humans, and are already using spaceships to abduct hillbillies and leave pretty designs in cornfields, what does that say about us?
It’s enough to send a holy man into an anxiety attack. Is there life on other planets? Did God visit them? And, if so—does He like them more than us? Every religion has had to tackle these problems and, of course, the most important problem of all: If there are aliens on other worlds, how are we going to track them down and convert those heathens?
