that myth from my childhood that we'd all talk about as xians
Exactly! IF the Garden of Eden story is a myth the whole caboodle is hypothetical so it doesn't matter. JWs need to have someone to blame (mainly now to cover up their own mess), so why not blame Satan!
Assuming the Garden of Eden story IS true, would you really want to thank Satan for giving us this life? Undoubtedly there ARE some beautiful moments/times/experiences but they are temporary. There is more anguish than happiness overall, I should say. That's nothing to be thankful for. Rather, I would like to thank those who have laid down a path on how to overcome this suffering.
