Not sure where this originally comes from. I spotted quoted without attribution one a friend’s Facebook page. An excellent point:
An example of a cataclysmic but barely documented event is the eruption of Mt. Vesuvius in AD 79 that destroyed two major cities and their surrounding settlements, killed possibly tens of thousands of people, had an ash plume that could be seen for hundreds or even thousands of miles, and yet the only written record comes to us from a single eyewitness, Pliny the Younger, who put his account to parchment several decades later at the request of his friend Tacitus. That pretty much puts an end to the “If the miracles of the Bible were true then more people would have documented them” argument.
