Forgive me as I sit here shaking my head. CATS you know, Cranial Agitateus Toomuchus Syndrome
Frustrating, ain't I?
Do read the article I linked. The fact that the entire Vatican was bulit upon a graveyard certainly doesn't help! But in the author's estimation, if we found a tomb near graffiti talking of Peter, that is near masonry marked with the approximate right date, of a 60-70 year old man, with some remnants of fine purple and gold cloth, we can surmise that it is Peter.
But I could never convince you scientifically of that.
