Christianity Explained

On my Twitter; responded to by someone who said, of The Daily Grail's post of the following: Illustration and caption, Christianity explained that "I think this says more about atheists than Christians. I dare you to say the same about Islam." I don't understand the atheist reference, but it sums it up for me. After all, the Christian myth is about a man, human, er, God, no wait, there's only one God, but he's up there, yet down here, .... oh, never mind. Many sacred myths predating Christianity with the same story. As far as Islam goes, they in turn took much of Christian and Judaic myth and turned into their own. As humanity does.
