What i find as a dishonest acceptance of written history is that most atheist will choose one documented account, yet disregard another solely based on the societal accepted version.A example of that is the earliest known references to Alexander the Great were written 250 years after his death, while Even if you don't want to accept non Biblical references,there where other non-Biblical references written within 100 years after Christs death.Yet noone questions whether Alexander the Great really existed or was just a mythical character but they question whether Christ did.
