Stellar,

Are you serious here? Just because artwork portrays Jesus as being pierced through the hands, while he was much more likely to have been pierced through the wrists, doesn't really amount to anything. The most you could say is that the artists in question didn't have sufficient knowledge of medicine. Being that much artwork depicting Jesus' crucifixion was done at a time when crucifixion was no longer practiced, one would understand if folks didn't have the details of physiology straight.

All that aside, how does a mistake in the depiction of Jesus' death show Christianity to be false? As a Christian, I can tell you that whether Jesus was pierced through his hands or his wrists is not some important part of our faith, and it never has been. I mean, it is common knowledge that the Romans ran the nail/spike through his wrists, but in the end Christians are much more concerned with the fact the he gave his life sacrificially for the world's sins and to reunite God and humankind through that death.
