Indeed Jésus isn't fictional he is a historical character (even if proofs of his existence are scarce), but he was an incredible successful mythomaniac since millions of people still believe in his fairy-tale and a pathological liar much like Muhammad, Moses, Hercules, Zarathushtra, Akhenaton, Joseph Smith, Simon bar Kokhba, Mirza Ghulam Ahmed or Hong Xiuquan.
Pretty much every historian agrees Jesus was a person. Whether he could do miracles and was the son of God...we cannot prove that outright. But saying he didn't exist is the epitome of idiocy.
The Old Testament god would have the Israelites take Superman on, then have them do some stupid shit that's designed to show their faith and then God would annihilate Superman (which he could have done from the start).
what thought reasoning would lead you to deny Jesus being the son of God, but not deny that God may exist? Doesn't seem coherent to me, unless what you meant is that you deny specifically the existence this particular Bible God, but don't deny the possibility of a higher entity.
Indeed you got it, I do not believe in the biblical God. I am deist: I reject both revelation and authority as a source of religious knowledge with the conclusion that reason and observation of the natural world are sufficient to determine the existence of a single creator of the universe.
