Surprising fact: Christianity grew roughly 40 percent per decade for its first three centuries, from a few hundred followers to millions, without state power and under persecution. That's among the best documented growth curves in antiquity.
My opponent notes atheists outscore believers on religious knowledge. Granted, but that measures facts about religion, not whether its claims are true. Category error, not rebuttal.
On unfalsifiability, I already conceded embarrassment proves sincerity, not resurrection. My claim was narrower: the sources are early, independent, and hostile to their own authors. That's the historical standard for any ancient figure, and they haven't met it. They win the sociology. I'll take the docket.
