If existance of parallel universes proved,then we will be able to prove that there is no death and we can just move from one universe to other..It should be a " unkown form of matter" that is moving from one to other universe and in one universe itself which we called 'life'.If we can discovered this form of matter,we will be able to say that there is a collection of 'matter' or 'life' that is the reason of our existance.
Because something must be common among universes ,if we can discover different universes.
