Jesus Christ's life and death is a matter of Western Civilizations historical record. Judeo/ Christian truths founded our nation. Read the writings of people far more brilliant than most today.
But his status as a deity is a matter of mere conjecture, unproven and unprovable. This supposed status was the crux of your statement. The historical existence of a man by that name is not germaine to your argument. Judeo/Christian ideals (not truths) figured in the philosophical basis for our nations founding to about the same degree that pagan Greco/Roman ideals did.
Your earlier statement remains unproven.
