Aslief: As I understand it The Greek Gods, Roman Gods and Assyrian Gods,Egyptian Gods, etc etc were all reincarnations of the same ideas over and over. As for Nancy, the Channel, If Id been her I would have just said:
"Ye shall have no sign save the sign of Jonah....the Lord must test thee, sift thee as wheat". Its worked lots of times before. If only SOMETHING had happened on one of the predicted dates, a massive earthquake say, she could have maybe got away with it.
