By no means a new topic for discussion but always worth a fresh airing . . .
I'd suggest that the 1st century was quite a well documented time. We have lots of historical evidence for important people who actually existed.
People like Julius Caesar for example. We have writings by him, and writings about him written during his lifetime. We have contemporary sculptures and artwork so that we have a pretty good idea of what he looked like, and various other artifacts confirming his life and death.
We have a known year of birth and a known day of death. In truth, we have quite a complete history of Julius Caesar which surely must give some pause for thought for thinking Christians when they consider that as yet no such evidence or complete historical record is found for Jesus Christ, who is supposed to have lived at a similar time (even a few decades later).
We don't even know Jesus last name.
