The Shroud of Turin has been the source of much research and disagreement. Most of it is based on determining the actual age of the shroud. I'll assume it is actually the required age, and not some artists depiction of a crucified man. Where is your proof that that particular shroud was Jesus'? What says it isn't the shroud of one of the thousands of other people who suffered the same fate? Even if it is the authentic shroud that Jesus was wrapped in, what is it about that shroud that proves he was the son of god?
