Cavemen put palm prints on their walls, beating your banana trick by tens of thousands of years.
The scientific tests done on The Shroud of Turin show much more improbable forgery then your inked banana and explain the detail.
It is always amusing to see people get desperate about what they don’t believe, as if what others belief causes them turmoil.
So, my statement of fact (the fact is, I don't believe the Shroud is what it is claimed to be) makes me a bad person, or someone to slur?
I'm just of a different opinion
