If you watched The Lord of the Rings: The Fellowship of the Ring, then you should know the scene where Gandalf makes his escape from the tower of the treacherous chief wizard Saruman. Saruman has joined himself with the dark lord Sauron, who wants to rule over all Middle Earth. Gandalf went to Saruman expecting to find a friend and instead met the enemy. Just before Gandalf jumps to freedom atop a giant eagle, he tells Saruman, "There is only one Lord of the Ring, only one who can bend it to his will. And he does not share power."
I guess the same is true when discussing the origin of the universe.
