There is more historical documentation of Christ than there is of Alexander the great. Many of these reports come from non followers of the time. Josephus the first century historian being one of them. That Christ existed is not in doubt. Billions of people believe him to be the messiah. This one man changed the world like no other. You may not accept him as God, but his existence on the planet is not a maybe. Almost all of his early followers went on and spread his word knowing that they would be mocked, tortured and killed. Why would they do this.
