Lucas was aiming for a Virgin Birth scenario, what with Anakin having no father and being the Chosen One (i.e. "annointed one," literally "Messiah" or "Christ"). An Immaculate Conception makes no sense, because there is no JudeoChristian God (that we know of) in the Star Wars universe, and there is no reason to believe that Star Wars humans are descended from Adam, one of that God's creatures. Even if the idea of an immaculate conception did exist in the Star Wars universe, in a more general sense, Anakin's conception certainly wasn't without some original sin -- he was created by Sith magic, which is about as sinful as you can get. So while the Immaculate Conception theory had some small hope of life before 2005, RotS blew it out of the water. The idea should be discarded like the nonsensical speculation it was.
