Doug.....I think you should do a study on astrology....as you will find it is behind the whole bible.
The reason Eve is linked to the apple ......is this....Eve isn't/wasn't a real person....She represents the fertile female principle.....she is the planet Venus.
Venus/love is represented by the 5 pointed star pointing upwards......that is why the 5 pointed star is pointing downwards in Satanism....it represents hate.
In apples you get the 5 pointed star also.
In the above you will notice Venus has a connection to apples......and that is just Eve(nus)....Satan (the serpent) is the planet Saturn and Adam the planet Mars ...and the Sun...(the male principle).
And they all come together to make the story of the loss of the light part of the cycle....or the fall of the sun.....in the daily cycle...this is evening....in the yearly cycle....this is autumn/Libra.
The Egyptian God "Atum" is the God of autumn....(you can see his name in there).....he brings to a finish the 6 months of light...starting from the spring equinox and finishing at the autumnal equinox......called in freemasonry...."the royal arch"
"Atum" actually means "the finisher"....of course it does....he ends the suns reign on earth in the northern hemisphere.

Atum/atom/autumn/death also becomes the destroyer of worlds.....as Oppenheimer rightly said talking about the "atom" bomb.
