Before I adress this, can I ask where this question is coming from? I'm asking this because this is a recurring talking point among those who reject the historicity of Jesus, and disingenuous questions regarding the historicity of Jesus are quite commonly submitted to this subreddit, and I've more than once made the mistake of engaging with someone who was just looking for an argument. I'd like to make sure this isn't the case before I put the required effort into formulating an answer.
