The 5 Elements start with the day that all the people began to hate each other and began groups, that groups would be later on the nations that would kill each other. Before all of this everybody could bend all the elements, and there were a few special people who could also bend elektricity. Later on there began a group that wanted to kill the people who could bend elektricity. The elektro benders fled and were never seen again ever since. Life went on and everybody lived in peace again until people began to invent machines. But the machines needed elektricitie, and the knowledge of the people wasn't far enough to make elektricitie. Everybdoy started to blame each other and the groups began to excist. Every since then everybody that was out of your nation was the enemy, or atleast that's what's you learned.
