A parable, if you will:
Second Law of Thermodynamics: the energy in any closed system tends, over time, to decay to a state of maximum entropy, i.e. maximum disorder. When this happens, the energy in the system is incapable of performing any useful work within the system. This means, pretty much, that the system has reached a state of maximum uselessness; it is of no further use to anyone.
Any fundamentalist Belief System (or BS) is by definition a closed system, since within the system no change or modification is permitted.
Therefore, any fundamentalist BS will, over time, inevitably decay to a state of maximum entropy, maximum disorder, and maximum uselessness.
The Universe is also, by definition, a closed system.
From this it would appear that any attempt to impose a fixed, unchanging Order on the Universe, will over time inevitably result in maximum Disorder; which, depending on how you squint at it, might at the present time be construed as either A Good Thing or A Bad Thing.
According to the Book of Genesis, “God” attempted to impose a fixed unchanging Order on the Garden of Eden, which he evidently wished to be a closed system. The inevitable conclusion from this is that “God” didn’t understand the Second Law of Thermodynamics, which he supposedly created along with everything else.
This in itself is grounds enough for suspicion; but it would seem that the real hero of the Book of Genesis is the Serpent, who spoke the truth (“Thou shalt not die”) to Adam and Eve - despite knowing that “God” would punish him for it - and who thereby provided the means for human beings to break out of the closed system of Eden, push the inevitable entropic decay of the Universe into the far distant future, and allow History to happen.
Any reasonable reading of the Garden of Eden story (recognising, of course, that the story is mythology and not history) makes it painfully obvious that “God” is definitely The Bad Guy here, who wanted the humans he had created to remain stupid and ignorant, so that they’d be no trouble. When they ate the Fruit of the Tree of Knowledge and became intelligent and uppity, they were of no further use to “God” as slaves, so he kicked them out of the Garden to find out stuff for themselves and take responsibility for their own decisions; which, from our point of view, was the best of all possible outcomes. A lazy, untroubled life in the Garden might have been OK for a while, but eventually it would inevitably (due to natural entropic processes) have become thoroughly boring; the descendents of those who accepted the Serpent’s Challenge (“thine eyes shall be opened”) became witchdoctors, shamans, artists, alchemists, witches, wizards, Natural Philosophers, and - eventually - scientists, technologists and engineers.
So by any intelligent standard, eating the Fruit of the Tree of Knowledge wasn’t in any sense, Eve’s (and thus humankind’s) first “Sin”; on the contrary, it was Eve’s First Good Idea, and we should all be suitably grateful to her for it.
