Even if the shroud was authentically proven to come from 1st century Judea, this would only show that someone was crucified, and crucifixion as a common punishment at the time has never been disputed.There would be no reason to presume it was Jesus in particular.

The two attributes central to the shroud’s alleged religious significance — that it wrapped the body of Jesus, and is of supernatural origin — are precisely those neither science nor history can ever prove.

The Shroud of Turin is a length of linen cloth claimed by some members of the Christian community to have been Jesus's death shroud.

The provenance and authenticity of the shroud has been debated for many centuries.

There is no record of where the shroud came from before the 13th century, and indeed scientific dating tests have shown it to be from around that time.

Sindonology is the "scientific" study of the Shroud of Turin.

Unfortunately, most of this "science" is directed at trying to prove that the shroud is the actual burial cloth of Jesus Christ, making it on par with Lysenkoism in the sense that it is attempting to prove the already falsified.

The Shroud is rectangular, measuring some 4.4 by 1.1 meters.

The cloth (specifically linen) is woven in a three-to-one herringbone twill composed of flax fibrils.

It shows faint but distinctive sepia images of the front and back of a naked man with his hands folded across his groin.
