Life = Consciousness = Energy = All there is
Switch your conscious mind off and nothing exists.You may think life exists even after your conscious mind becomes unconscious. But you would have to be conscious to have this realization, unconscious state of mind theoretically makes it impossible to perceive "all there is". However on the contrary, since consciousness is "energy", energy cannot cease to exist, but can only change in state. Therefore makes you an eternal conscious mind. Hence you perceive things therefor all things exist and expands. That's just one perspective of looking at life through the infinite amount of possible explanations and variations thereof there may exist about what life really is.
