There there are numerous contemporaneous references to Caesar and his activities. And they don't contradict one another. Further, his Commentaries on the Gaulic Wars is intact. There are no apparent gaps in the text, and no apocryphal chapters floating around. It was an important work in its day, and it was never lost or out of print. No council was convened to arrive at the official text. It's as absurd to doubt Caesar's life and work as it is to doubt George Washington's (we even know that the cherry tree tale was fake and who faked it). The Bible, and particularly the life of Jesus, has virtually no external contemporaneous references (other than Josephus). Well, we know Herod was real from other sources. But I don't doubt the life and work of Jesus, so I don't really get your point.
I was answering a quesiton posed in Post 59 as to "How do you know that the Bible is accurate."
It's as objectively reliable as any book in antiquity.
