I am genuinely curious, and as this could be said about many stories in the bible, I have never really heard of what historians may believe to be true about his life when you exclude supernatural phenomena from his life story. What may have been people's explanations for things like walking on water or turning water into wine, etc.
I'm not completely sure what you were getting at with your question phrasing, and might have removed it if not for the clarification of your post, but would like to emphasise: the point of AskHistorians is to ask questions of experts who can make arguments from scholarly literature and/or primary source material, and their religious faith (or lack thereof) is irrelevant to their qualifications in that regard. If you were meaning to ask exclusively non-Christians to respond to your comment, that is not something we would permit.
Having said all of that, it sounds like what you're asking for is whether or not Jesus existed along the lines of the Bible's description of him - and to that end you might find the answers in our FAQ useful.
