The Sherman, do you believe the historical writings of Caesar - e.g. the Gallic Wars - to be accurate ?
There is more documentary evidence for the New Testament than any other ancient writings. So why do so many people reject it out of hand, yet will happily believe that Caesar threw his armies against a stronghold admirably fortified by both nature and man.
Why, in the first 100 years after Christ, INVENT a religion, unless something extraordinary happened. Why have 4 differing and occasionally contradictory accounts ? If I was going to invent a religion, I'd pay more attention to detail.
