The existence of Jesus Christ was attested to by numerous witnesses and the fact that twelve of them at least were willing to die horrific deaths rather than recant what they saw and heard. Later on disinterested historic authorities such as Josephus took his “existence” at face value. Who would be willing to suffer such a fate for the sake of Richard Dawkins and can anybody swear they’ve actually met the SOB? Anybody?
it is not the eye witness accounts but the actual written records of the day. For example the romans actualy kept written records of who was crucified and when.
