Tom, although faith in homeopathic medicine and faith in religion are possibly comparable, there can be no comparison between those beliefs and the question of whether or not ghosts exist. The first two are based on faith and the last is based on the evidence of ones's own eyes. Since I have no evidence that faith in the word of the bible is justified, I argue against it. However, I have seen a ghost and therefore I cannot deny they exist.
You're putting words into my mouth Tom. I didn't say we do not have good down to earth explanations for the appearance of ghosts - I said I don't believe that everyone who claims to have seen a ghost is either lying or hallucinating, and I think one day science will find an explanation. I'm sure there are often logical reasons for some of the things people claim they have seen, but in my case, no - there was no logical explanation. It was a ghost. Sorry, but there you have it.
