The Shroud of Turin
This is the one that fascinates me the most. The Shroud is a 14-foot long cloth with the impression of a man who’d endured horrible pain by crucifixion. The origins of the shroud are murky, but it’s generally believed that the image on the Shroud is of Jesus Christ. This theory hasn’t been formally accepted by the church, nor has it been debunked.
There have been tests conducted on the cloth and while it dates back to the Middle Ages, others claim that the energy required for a man to come back from the dead, would alter the shroud to the point that radiocarbon dating would be misled. Other factors, such as the bloodstains, the pollen found in the weave, and the positioning of the injuries, have been subject to debate.
