How do we know Jesus was a real person ? is there any contemporary literature with eye witness information ? No,
no person wrote anything for 100 years or so, except the fact that Jesus is pure fiction just like H.Potter.
There is no mention of Jesus in Roman records, no mention of him in crucifixion records, a man who supposedly walked on water, rose from the dead ,made cripples walk & the blind able to see & yet nobody wrote a single word for decades??????
Philo (20BCE-50AD) wrote 800,000 words on 30 manuscripts about Jewish life and on god, but failed to mention the god-man who supposedly performed miracles near where he lived.
