Bible stories are all plagerised from older Sumerian legends.
here is a link that shows that there were apx 25 cultures that have FLOOD legends similar to Noahs Flood.
the sumarian account only dates back to 1700 BCE
thats before AD in case you didnt know or apx 3700 years ago.
http://en.wikipedia.org/wiki/Flood_%28mythology%29#Sumerian Platos account of the Ogygian flood is said to have covered the whole world and was so devastating that Attica remained without kings until the reign of Cecrops
http://en.wikipedia.org/wiki/Flood_%28mythology%29#Greek the Mediterainian has been dry three times over the ages which corresponds to the three greek accounts of the Floods.
another interesting point is the mayan account that paralells the biblical accounts of the flood and later on the tower of babel
Huracan ("one-legged") was a wind and storm god who caused the Great Flood (of resin) after the first humans (made of wood) angered the gods (by being unable to worship them).
Huracan / huricane?
the first humans angered God by not worshiping him.
http://en.wikipedia.org/wiki/Flood_%28mythology%29#Maya all of these accounts could not be coincidental
especially when considering the distances between the cultures.
it points me to think that people went underground because of the ice age and that people did interact with each other around the globe before that time.
otherwise how could so many different cultures have similar legends.
