You haven’t yet explained why the question is significant.
Because the Shroud is not a photograph.
You said science “discovered that it was a photographic negative”.
A photographic negative IS a photograph - so I’ll ask again: do you believe photography existed back then or not? (Hint: it did not.)
The significance is that without photography, there couldn’t be a photographic negative, unless it was a miracle.
Which gets back to my original question - Is it science or a miracle?
And by the way, if you say it was a miracle, I’ll respect that, since it was never my intention to make fun of someone’s faith - I only meant to make fun of fake science and circular reasoning.
