Excellent point about the iceman mummy. Did it suddenly convice the society that people lived in Europe prior to their date for the flood? And his body could hardly have survived with all the tools, charms, and arrowpoints if the flood had washed over him later.
This Oetzi is a fossil of reality. They choose to not believe it.
Ark is a "fossil" of failed expeditions and tabloid legend. They choose to believe it completely.
Maybe we should also ask "what would happen if they revealed the UFO in area 51"?
I think most people would find a way to agree or deny based on their prejudices. Just like the WTS and Oetzi.
