Christianity makes you very angry.
Ancient authors usually mixed historical factoids with myth, allegory, hyperbole. They did not write analytical history. You are using modern standards and applying them to ancient people.
You only apply your hyper-skeptical standards to Christian authors, but to no one else.  That calls into question your impartiality.  I've never seen you write that historians should throw away Herodotus and the Norse Sagas because they mix mythology and hyperbole with nuggets of historical data.
I notice you did not dispute my statement that whether or not one takes walking on water literally, it does nothing to change the core essence of Christian doctrine concerning faith, grace, salvation, ethics.
I don't think there is a militant atheist on this board who hasn't tried to pull the trick of equating Christian belief in Jesus with ancient pagan belief in Thor, Odin, or the Sun god Ra. 
That is a terrible analogy because it ignores that the intellectual basis of religions like Christianity and Buddhism are based on historical claims about historical people.
