Thanks for writing David. Those are good questions and I have to say my jury remains out.
I have watched several interesting documentaries about Jesus living and being buried in Kashmir. These are easily found on YouTube and offer some compelling evidence. It is claimed he did not die on the cross but was taken from the cross still alive had to heal deeply and was well looked after by Joseph of Arimathea, both Marys etc.
After a long recovery, they say he took the Silk Road east and is referred to in Tibetan monastic literature etc. after long travels.
I must say it was fairly convincing!
