The most documented legal historical evidence prior to the printing press is the life, death, and resurrection of Jesus. Do some research.
Flavius Josephus wrote in 93 AD, what would he know first hand of a Jesus?... and what little he did write is disputable.
Some 20 yr later we then have Roman politician dudes Pliny and Tacitus, but if you study scholarly Roman empire history, which often references them, we find their accounts of significant Roman empire details at times vague, sketchy, incomplete, innaccurate, and in conflict with others accounts.
They are not an absolute or always reliable source on The Romans themselves, far less so for scant details on a much more vague and far less relevant Jesus character.
>> Which ancient non-religious sources of scholarly repute of such period give account of a Jesus doing miracles, resurrecting, and dissapearing in the sky?
