Was the death of Jesus a set up?

If the question is whether Jesus did not really die, but that someone else died in his place, that was certainly a belief among some Gnostic Christians. However, modern Christianity is based on the belief that Jesus really did die on the cros and really was resurrected on the third day.

The alternative is that the crucifixion of Jesus of Nazareth was a literary creation, based on older myths of the crucifixion of Near Eastern deities. Even today, some say that perhaps the real Jesus was not actually crucified.
