There are numerous personal testimonies of seeing UFOS's that you cannot say are embellished or embroidered or conflated or anything like that. They are just testimonies directly recorded by the observer. For example, many air force pilots and other pilots where what they observed and swear is true was officially recorded and documented.
Same with ghosts, seances, ouija boards, stigmata, remote viewing, faith healing etc. Some of these have been examined by the most sceptical minds who have done rigorous independent testing and concluded there is nothing in our current scientific knowledge to explain it.
None of the arguments on this thread proves that UFO's or gospels are real or false. It just proves there is a lot of room for doubt, and that a sceptical position on highly unusual, miraculous events in ancient history is entirely reasonable, but that there are also some reasons to restrain that scepticism, because of the existence of unexplained phenomena. Being thus entirely sceptical or choosing to limit your scepticism, you can then choose to reject it all out of hand or allow some room for belief in the possiblity of 'events' in the ancient past and present for which we have no possible explanation but no way of proving either way. There's no need to put religious or other definitions on it. Just call it unexplained phenomena or events.
