The so-called parallels [between Jesus’s virgin birth and earlier pagan myths] are not parallels at all! Perseus was not really virginally conceived at all, but was the result of sexual intercourse between the lecherous god Zeus and Danaë. Zeus had previously turned himself into a shower of gold to reach the imprisoned damsel. Zeus also fathered Herakles from Alkmene and Dionysus from Semele. Similarly for attempt to assert that the Resurrection of Christ was plagiarised—the death-rebirth-death cycles in paganism have nothing to do with the once and for all resurrection of Jesus, and the pagan gods didn’t die for our sins. And the Osiris legends have him remaining buried in the ground, while it’s a historical fact that Jesus’ tomb was found empty. Other alleged parallels are just as worthless, so it is pointless for sceptical scholars to multiply examples—zero times a hundred is still zero.
