Interesting. I thought it was fairly well established that Jesus existed in some capacity but the debate was about who he actually was and (from a religious standpoint) if he did any of the things the Bible claims he did. It's interesting to read that non-jewish people of the time seemed to have no knowledge of his existence.
At the same time though, I wonder if it's possible that most people just ignored him, which is why there's apparently very few accounts of him until after he supposedly died, resurrected and ascended to heaven. Kinda like a street preacher in Times Square, NYC. How many people actually acknowledge street preachers on social media, and how many of them actually know the preachers by name? Then think about how social media didn't exist yet, so the bar to be recorded in history by uninterested third parties (even just as a letter to a friend about that "annoying Jesus guy") is probably a lot higher.
Not saying he existed, just that it's interesting to think that he could have existed but the lack of evidence is just because no one gave a fuck.
