I hope that you are able to specify how and in what way Christianity is 'unique' in a clear manner. Skeptics (and 14 year olds with Google) are always so quick to jump on the 'similarities' between Christianity and other pagan beliefs or simply it's comprehensibility(?) to Mankind to argue that Mankind must have made it up. I guess in their minds only a belief system totally alien and incomprehensible would be true and adopted by billions. Heh.
