What to doubt?

...the number of surviving manuscripts of the Gospels is staggering in comparison to other ancient works. As Roberts notes, “The number of Gospel manuscripts in existence is about 20 times larger than the average number of extant manuscripts of comparable writings.” This figure does not even represent the hundreds of thousands of quotes from the Gospels in the writings of the early church fathers. We have nearly 2,000 manuscripts of the Gospels alone. This meant that to doubt the reliability of the Gospels is to doubt the reliability of nearly every ancient text that we have.
