I believe the answer is that as Adam & Eve committed a sin whilst perfect they simply now cease to exist and have no resurrection.
The problem I have with W.T theology is how a person created perfect can do something imperfect? The witnesses will answer "free will" . But free will and perfection are clearly not the same thing.
As for the actual sin, in my viewpoint the story is that God gave them a choice. To clarify we're they :-
A) told simply not to eat from a tree.
Or
B) given the choice to eat from the tree, with the consequence of doing so explained.
As the answer is B, how then did they disobey God?
As for the consequences of that choice now, shaping the world we live in today, was this in your opinion even remotely explained to Adam?
