Jesus ain't no Myth, ain't no fairytale, and certainly ain't no legend.

A lot of us will say, I don't believe in God, Jesus, or Christianity, because I think it's all made up - just another myth, fairytale or legend... well Jesus weren't no Myth. Is God real? Was Christianity just made up - invented for control, money, and power? Was the God of Christianity copied from other ancient mythical gods such as Mithras, Horus, and Dionysus? Is there any historical support to this claim? What do the scholars say?
