Your hypothesis is: "This rag is the burial cloth of Jeebus"
This implies, that it has to be 2000 years old.
If it can be shown, that it is not 2000 years old, your hypothesis is falsified.
C14 clearly shows, that it is not 2000 years old, your hypothesis is falsified.
You can now either show the rest of the world in general and the scientific community in particular, that C14 tests have no use, or you can accept that The Rag Of Turin is not, and never has been the burial shroud of anyone living 2000 years ago.
In which case it does not matter, who you claim to have been wrapped in it.
But you have been told this a zillion times already.
Why do you want to be "scientific" and "prove" anything?
You fail each and every time.
"I am a believer, my faith is central and I ignore anything but my faith" would be much easier for all involved, and would spare you defeat after defeat.
