If the 'Ghost of Times Passed' [citation not needed ] visited you one evening and allowed you the chance to revisit one brief moment in history and witness it for yourself, with the purpose of unclouding or discovering unknown events -- which moment you choose? Let's say you have an hour maximum before you head back to the present. It can be for any benefit. -- (Assuming the ghost had a valid place to take me) I would ask to visit the scene at Jesus' supposed place of resurrection. I would sit in the cave 5 minutes before the event was said to have taken place and watch for myself, returning with divine rejoicing or despair. Even knowing it'd be logically impossible for others to credit the details I brought home, I'd still take the burden.
