It's not whether named individuals like Moses, Buddha, Zoroaster, Jesus and Mohammed actually existed and acted in precisely the manner asserted by their most literal (and therefore cultish) followers. Rather, it's whether, for the people of the time and place where these religions arose, the prime figure represented their idea of how the perfect person would act in the universe as they then understood it.
If enough people believe a substantial holy book literally, then someone else can comb it for odd verses that fit his personal prejudices (just think of the criminalisation of homosexuality) to achieve wicked ends.
Most of us here are prepared to take a whole set of strange concepts very seriously - I don't find the Jesus story incredible, just horribly politically convenient - so should we think of Jesus as just one more paranormal phenomenon? The difference (for me at least) is that the phenomena we concern ourselves with at Skeptiko are not one-off events that support human institutions with all their flaws. We are trying to look at the phenomena of consciousness as carefully as possible - mainly looking at phenomena that are repeatedly reported.
If (say) Eban Alexander were the only person to have had an NDE (or even one of a very small number of historical figures), and his case had been written down 2000 years ago, then I'd be just as keen to abandon 'Ebanism' as a myth, as I am to abandon Christianity as a myth (or as some very distorted record). If 'Ebanism' had evolved into a consistently kind and considerate religion, it might be enough to strip it of its historical roots, but we know that Christianity has a morally very mixed past - inspiring the very best to the absolute worst of human behaviour.
Thus I am with David Fitzgerald, until he gets to the issue of consciousness, paranormal phenomena etc. Clearly he hasn't really studies any of these phenomena, and just takes science at its word when it tells everybody to walk on - nothing interesting to look at here! I used to think that way myself, and I really hope he can be persuaded to browse this forum - exploring the many links which it contains. Perhaps his enthusiasm for the truth will lead him in a new and fascinating direction
