Dawkins is like a man blind from birth arguing passionately that there is no such thing as the color red.
If God does not exist, then the Son of God could not have existed on earth either. Right, Mr.Dawkins? So why then go on to discuss His possible existence?
Who in his right mind would create a story featuring a man who would claim to be the Son of God to the point of allowing himself to undergo the most brutal of unnecessary deaths? Who would want to hear such a story? What possible purpose would it serve? What moral could it teach? What goal could it possibly have? There is no rational reason for creating such a lie, much less dying for it. Yet thousands have died for it; thousands more will. Are they all dying for nothing Mr. Dawkins?
