With regard to disproving the resurrection of Christ, it is possible that
historical documents could be found, (as was proven by the Dead Sea Scrolls
some of which antedate Christ) which would offer evidence of eye-witnesses
that the body of Jesus was seen and was decomposing even after "the third
day." Depending on the nature of the reports, such documents could at least
bring the resurrection into serious question. The resurrection is thus at
least theoretically falsifiable.
