Perhaps not 'definitive', but Gerald is seriously reconsidering reincarnation in the light of his reading of two books Irreducible Mind and Beyond Physicalism, and the work of Ian Stevenson on past-life memories. That is to say, on scientific studies and actual modern evidence. Perhaps you should discuss this with him.

I certainly haven't studied the evidence for the resurrection in as much detail as you. Given that it is said to have happened so long ago, it is hard to see what progress could be made now. Are you sure that you have freed yourself from all cognitive bias on this issue?
