But God commanded them to not eat the fruit of the tree of eternal life and of the tree of knowledge of good and evil. Yes, this is a parable, not actual history. But in this parable, God commands that Adam and Eve not eat the fruit. I don't see where God presumed that they would ultimately disobey. As punishment, he banished them from the Gaden of Eden, unable to return. They never got to eat the fruit of eternal life.

Again, I see this parable as being about the coming of age, so the above discussion is merely academic.
