I think there's reasons to be skeptic about the historical Jesus. Not exactly 100% certainty but many records are confusing... You see, even if we assumed someone with the name Jesus was baptised and then crucified there were so many people with the same name at the time and so little people who knew how to write and read correctly that the probability is lowered significantly. I don't think it's wrong to think someone similar to the bible character existed sometime and inspired the holy scriptures but there's lack of evidence to at least be distrustful about the existence and life of Jesus or if it's the same person altogether
