You just need to use your imagination. The war in heaven starts on July 28, after Satan interferes in Earth matters one time too many (sorry, Archduke Ferdinand!) and Yahweh has gotten a bit soft and lazy, so he lets the battle go on way too long. Finally, in early October god decides enough is enough- he snaps his fingers and WHOOSH! Satan and his demons fall to Earth. Then god presses his Easy button and gets back to watching movies.
I mean, I'm no Joseph Smith, but that's not such a bad interpretation, is it?
