So your refutation is, “I can make up a hypothetical which doesn’t exist except in my imaginaton, and that’s enough to refute something which has been extensively documented and studied by numerous scientists in the 20th century using multiple techniques across different fields.”
You stupid troll.
No, I’m just laughing at the circular reasoning on this thread - people who believe the image of the crucifixion on the Shroud is a photographic negative. And that somehow proves the artifact must be legit - because it captures a historical event from a time when photography did not yet exist! LOL.
Make up your mind priest; is it science or is it a miracle?
