You're missing the point of the OP. It isn't saying is Jesus a metaphor, it's suggesting is the crucifixion a metaphor....there's a big difference.
no, I am saying not only did he exist, he died on the cross, it is not a metaphor.
Historians have been studying all the evidence we have, all the text from all sources such as writings by skeptics back then who discredited Jesus's miracles and him actually rising from the dead, census's from the time period, writing of the high officials, and all sorts of stuff.
Skeptics back then would not have discussed his rising from the dead as being a hoax and his body was just stolen from the tomb, if he didn't exist or died on the cross in the first place.
They couldn't discredit it because it happened, they discredited him rising from the dead.
It would be like skeptics today claiming 9/11 didn't happen and was a hoax.
No, they discredit what the gov says and blame them for the towers falling.
We know the towers fell.
Back then, they knew Jesus died on the cross.
