The beginning of the new world

When the old world "ends", what happens? Simple,The new world is created. When all the adults die, or are left on another planet, what happens? A new way of life is formed, with a new governing system, this one is all kids! Wonderful right? Of course, the new government must be able to deal with all sorts of disasters that the old government caused. Makes it so much easier to just move to a different planet right? The new world must also be fully supported by the survivors of the old world. Usually little kids will believe anything. Otherwise, things are just messy, and so problematic… the other option is world domination. In a world full of children, world domination should be easy. No problems....right?
