My understanding (from reading a book called "who wrote the Bible") is scholars generally agree Jesus existed, but out of the 5 main objective criteria for "did a character exist", he only satisfies 3 of the 5. IIRC, the fact that he plays so prominently in modern life acts as an effect size: in the 3 categories he can be confirmed, he is off the charts.

So it is generally accepted he existed, even if the criteria used to judge other historical characters is loosened for JC.

Edit - but please try to not say things like "ignorant" or "disabused" unless you meant to attack OP. Those are pretty loaded words for a collegial discussion.
