When we apply the quantum theory to the universe, we are then forced to admit the possibility that the universe exists simultaneously in many states.
Still no convincing reply to why this isn't simply our inability to detect the precise location of an electron. If so, it does not mean that it has no precise location and is, therefore, a magicy wagicy wibbly wobbly particle that exists in many places at once. It just means we lack the ability to see it.
