(sorry for the incompatible blank post)
my ponderings
whether there were two trees or just one tree, to me trees (and the snake) represent nature. The clothing that adam and even were given by God could be seen to reflect manufacture. God could be seen to be supporting civilisation.
edit: the snake living with humans is interesting (Josephus in cedars above hiya team mate). this would suggest, following my reasoning, that humans at first, bofore the advent of houses, cities etc, when humans lived in caves for example, that they shared their accommodation with snakes
