The "Jesus myth theory", that is to say the thesis that Jesus was either not a real historical figure, or if one not connected to Christianity, is certainly not a new idea. However I understand that this theory has had its ups and lows in terms of credibility during the last century. Is there a widely accepted consensus among academics today on this matter, or is it more nuanced and maybe prone to evolve in the future depending on continued research?
As always, more can be said, but I would like to recommend you look at the FAQ under very frequently asked questions ;)
