Did I miss something in the Silmarillion in regards to the 'Fall' of mankind?
And, to be a bit silly, Eru allows humans to escape the confines of Arda in order that they might escape the fate of being the subject of a movie sequel by Peter Jackson and company; something that in time even the Powers may envy ("Hmmm, just how can we make this
Silmarillion story more exciting...let's make it 10 jewels, add a back story of a romance triangle between Manwë, Varda and Melkor, leave out that Eru guy as he's not really important to Tolkien's main theme, add a few belching Dwarves and we might just have a hit! ").
And now back to the serious discourse.
