If you know a way to fake being crucified, let me know. Till then im willing to assume it hurt like hell. Literally.
They hammered nails through his hands and feet, put a crown of thorns on him, he just didn't feel anything. He was just acting for the crowd, pretending to be mortal, to be human.
If you saw the movie Prometheus, they hinted that ETs had planned to come back to earth 2000 years ago to destroy us because we did something to piss them off. We crucified to one they sent to earth to show us how to live. Jesus' super powers could be explained by excepting that ETs visited us, didn't like what they saw, the anger, wrath, and brutality of the OT, and hedonistic Roman society, and thus created a new mythology for, giving stories that would push us in a moral and right direction and become a better society.
History is reported to us by people who believe their personal account to be the one future generation need to hear -- thus unreliable as far as fact or accuracy. Four Gospels, only one mentions a virgin mother?
What's interesting is how much God himself shows up in the Old Testament and the New Testament is about someone who is the Son of God. And God himself only communicated via proxy, angles and Jesus.
