The latest Mars landing got me thinking... Imagine one day we figure out how to colonise Mars and the whole of Earth is evacuated before it is destroyed. What would happen to ghosts/demons etc here on Earth? Would they be destroyed? Would they come to Mars? If so, how? And if they can, do we assume that all planets etc are haunted? Please only respond if you're a believer, because replies saying it doesn't matter, they don't exist etc really won't add anything to this thread!
