If it was a global flood then it is simply impossible. If it was a local flood then it wasn't divine (just an ordinary flood or tsunami, etc). If jesus rose from the dead then that's impossible. If he was simply comatose then he was just an extroardinarily lucky man. Pick your position Doc. Were these things divine acts of a supernatural (and impossible) nature or were they natural events that were simply misconstrued by the people that experienced them?
