There almost certainly was a man from Nazareth named Jesus (we have pretty good unbiased sources there).
However, unless you are a follower of his (or potentially some related religions), there are obviously mystical things associated with him that you likely do not believe to actually have happened. Even followers disagree about the veracity of certain stories.
So where does that leave us? There is undoubtedly a “real” Jesus, but was he anything like the person we think we know? 2000 years of being one of the most famous people ever is certain to leave a skewed perception of who you are. Hell, we don’t even know the true story of celebrities and religious figures today.
Unfortunately, much of the discourse about this seems to be heavily biased, cloistered (literally), or commercial (Nat Geo and History seem to butter their bread with this topic each spring).
And ultimately does it matter? How many of the attributes stories would need to be proven false to make Jesus seem “not real”?
