When you think you are collecting "stupid and immature" (sic) replies, question your question.
By definition, a narrative of origins has to end up in the "reality" it was designed to explain in the first place. From this angle, "Adam" had to die because we do -- not the other way around. He had to get knowledge because we know. And so on. Any "if"-bifurcation artificially plugged into the story course ends in nonsense because the story has only one possible ending: reality as the author, storyteller, readers, hearers know it.
Even the later Jewish and Christian interpretations of the Eden tale as "temptation," "sin," "fall" etc. were generally not as shallow as to construe it as an "accident". For instance, to Paul the first, earthly, fleshly, dustly, "sinful" Man (Adam), was a necessary "first step" to the Second, heavenly, spiritual Adam (Christ: compare 1 Corinthians 15 and Romans 5). This is closer to an evolutionary pattern (in the metaphysical, not biological field) than to a restoration after an unfortunate loss (as per the WT interpretation).
