ok, first of all, the Bible is a historically accurate source. In it, you have 4 main writers testifying to Christ’s life, and His actions in life. Then, there are several more authors in there re-enforcing those claims to His existence. Furthermore, there are at least 4 historical pagan writers stating that there was a man Christ who lived and died, along with a score of historical Catholic writers, who testified to the same thing.
Many events in history are accepted without question with less testimony and evidence. For instance, nobody questions the existence of Hannibal, or even the life of Herod, or the life of Euclid. We don’t have their direct writings, only some records of them. Some of these records can be based on only one, maybe two accounts, and yet they are not disputed. Arguing in the face of all the authors and writers who wrote about Christ, in this light, would be bias. So, I wold conclude by saying yes, there is sufficient historical evidence that Christ existed. At least by modern standards.
Just in case anyone is still interested in this topic.
