the jews did not write it down but they still had oral history...
the timeline is still possible. Besides if you think that the idea was first the greeks then you can think that the hebrews copied the greeks or
whatever...
but still i think that there is a connection and ill give you some reliable sites.
i never said that every detail would be the same... besides each story would be changed to fit culture so of course there would be such differences.
From all the research the finding of giants cyclops unicorns, gos and alies etc are found in all cultures by dif. names and changed to fit the
culture. that doesnt nullify the connection.
