Original sentence: A number of historians have seriously questioned whether Jesus ever really lived, and while most religious and secular scholars presume his existence, many find the question of his existence undecideable by historical means alone.Both the Anno Domini system and the derived Common Era system of reckoning years have their origins in faulty 6th Century attempts to establish his birth date.He is also mentioned in a number of other works, mostly significantly post-dating the first century, and thus are of disputable historical significance.However, ancient historical and mythological figures are often portrayed only from references written centuries after their deaths.Those who have a more naturalistic view of history are particularly skeptical about events such as the resurrection of Jesus and (other) miracles mentioned by the Gospels
