Taken together I think the numbers of actual eye witnesses to the purported events in the gospel who actually saw (and could understand) what was actually written in the gospels decades later would have been vanishingly small.
What we do know, however, is that the events purported to have occurred in the gospels were not sufficiently compelling to mean that christianity gained a foothold amongst that community of eye witnesses. That tells you everything you need to know, really.
But considering Christianity is a world religion what makes non adherence of a small country (who have perhaps the most entrenched position of national chosenness) significant for it.
I think the trouble is your analysis of the resurrection as a sort of one of empirical and sensual event without due attention to the consequences of the resurrection and the ascension.
Clearly the vast majority did not witness this so there must be more to Christianity than an empirical sensual approach. Surely if there were not more Christianity should have just been reabsorbed into Judaism.
Going back to Christianity I think Christians would acknowledge they were not eyewitnesses to this but are witnesses to the ascended Christ. The resurrection then is not so much a mystery in this context.
Similarly with miracles in general. There have been great and faithful cessationists in Christianity who have held with the idea that If there were miracles, the age of miracles has past.
The position of many atheists on this thread is to make Christianity merely a question of the miraculous.....Diddle it so the miraculous, with the exception of the resurrection, is the key to Christianity and then tackle a straw man caricature.
In other words Davey there is IMHO no significance in Judaism rejecting Christianity and as a point of fact was Buddha not an Indian prince? and yet India is predominantly Hindu.
