Is entropy a real thing?

Since we cannot reach actual “zero” in temperature, does entropy exist, or is it just a theory? When we die, is it from a “loss” of energy, or just a fundamental shift?

What is existence? What does it have to be in order for it to exist?
To whom would it have to be made manifest in order to exist?
Does it still exist if we cant sense it? What is reality?
Does death exist? What is death? Ha anyone been back from the dead to tell the story?
Maybe point zero is simply transition from -1 to +1 Maybe we just spend a little time at zero.
Could death be that transition from one way of being into another?
