That part of your post above Hope: "regularly thrown at religion as having no external corroboration"? this is only thrown at religion because religion has no external corroboration? Be fair.
In fact, I'd say the opposite; let's take the example of Jesus' life, death and resurrection. Some here say that the latter is impossible because - humanly-speaking - resurrection is impossible. In other words, he either died and stayed dead, or somehow survived the cross and was somehow resuscitated within the rock grave (perhaps by the extreme overnight cold that such an environment might exhibit). If the former occurred, the authorities would have been able to produce the body. Did they? No. If the latter, is it likely that a seriously injured human being (remember the trauma that his body was put through) would have been able to walk around within 72 hours of such an ordeal, to the extent that the authorities couldn't find him? Humanly-speaking, no. What other possibilities would you suggest, ippy? Remember that the grave was guarded by a troop of soldiers, and realistically, the disciples had no expectations of a resurrection so would have no reason to bribe those guards and steal the body.
So the story goes - but on what basis have you excluded the possibility of propaganda?
Lets face it, there is nothing in this story that couldn't be fictional - whether it be the impossible bits, such as resurrection claims, or the routine bits, such as who might have seen what, who might have said what to whom etc etc. Even stories about real people can include fictional elements: such as North Korean dictators allegedly showing remarkable golf skills at their very first attempt: not believable though is it?
Some, or even all, of this story could be anecdotal fiction but I've yet to see any of you guys provide a basis for excluding this possibility. You seem to accept that it must be true by default, and also that specific aspects of the story can be used to confirm that the story must be true - so when you say;
...is it likely that a seriously injured human being (remember the trauma that his body was put through) would have been able to walk around within 72 hours of such an ordeal, to the extent that the authorities couldn't find him?
I'm wondering to what degree you have taken into account that this might not actually be true at all and that it could be propaganda. To exclude the possibility of propaganda in relation to Jesus, but be prepared to be more critical when it involves the likes of North Korean dictators playing golf or ex-American Presidents assuring us that they 'didn't inhale', is special pleading pure and simple.
