This "free will" in the first place is an invention of the same men who invented your christian god, if not so then where is it, is there will dangling from my back? Oh I assure you we are quite free, but the notion that the christian god made us so and gave it a name is laughable.
The story of Adam and Eve, taken for a record of our ancestors? Ahahah.. did you ever think how the races of the world stemmed from a couple of beautiful caucasians in paradise? Little more than a mythical fable, parable if you must, but history? Dear god, we are in a lot worse shape than previously thought if people really believe that nonsense.
