Debate of falsehoods without the foundation of the existence of the individual who, supposedly, created them is moot.  No Jesus, no debate.  All subsequent such "debates" are merely exercises in circular logic starting with a false premise and supporting it with equally false facts.  He didn't exist; therefore any teachings and claims cannot be supported without identifying the true sources of their existence.  A whole industry of "scholars" has existed since the Roman Empire era to "debate" to falsely portray an original false creation.  Christianity is nothing more than a compilation of previous human-created religions from pagan to animus to one god(Jew).  All incorporated into dogma and rites to con groups into joining.  If that doesn't work, slaughter them militarily until the remainder submit.  The entire illegal legality of "Christian Discovery" created by another Pope to give judicial justification for the conquest of all others in the world.  The existence level negates all.
