Wholly, this is the so called cognitive dissonance. You can have show them how much evidence/proof you wish, they just don't accept it. It will break their hopes of eternal life, so they can't handle such evidence. As she herself put it:"Lord whom shall we go away to? You have sayings of everlasting life"
Obvious facts doesn't promise eternel life, but the society does....therefore they prefere to belive the society, even if it is blatant lies.
