De acordo com esta resposta de DavRob60 sobre a questão do pai de Anakin.
There is a recently published book, Star Wars: Darth Plagueis, that supposedly answer this question. From Anakin Skywalker Wookipedia article
In addition, although Darth Plagueis did attempt to influence the midichlorians to create the ultimate Sith weapon alongside Darth Sidious, the experiment was ultimately a failure, and the midichlorians, sensing the Sith's inherent malevolent intention, not only refused to do so, but in retaliation, conceived Anakin Skywalker in order to destroy the Sith once and for all.
Parece que a força (ou pelo menos os midichlorains) agiu de uma forma Divina para criar Anakin Skywalker.
