Josephus documents the death of Jesus, although some dispute the acuracy of this. We have artifacts that call Jesus the King of the Jews, but he was not a historic messiah, as he did not overthrow the Roman government over the Jews. His dominion was not of the earth. As for his resurrection, the ministry of Paul and others testifies to the factual nature of it and the discovery of contemporaneous copies of his Epistles testify to his reality as a historical figure and his belief that he and others had seen the risen Jesus. Without such witness, Christianity would be a silly religion and the New Testament would be read with the Oddesy as ancient literature rather than theology.
