Blues brother, the answer to the jw retort that it all came from the same source etc is... The Egyptian, Babylonian and Greek legends have all been shown to pre date any written Jewish texts by centuries in some cases. From an archaeological viewpoint the Torah is very young.
So if "Jehovah" really wanted his law and name to be known then why did all these other ( far more advanced cultures) come up with the same ideas way in advance?
These other sources do not predate the creation of the first man ( as the bible would understand it) but they do pre date the time that the bible says man was created.
