Why do you think there are such innumerable microscopic details in you and in the cosmos—from the subatomic to the fact that no two lillies or sunrises or human beings are exactly the same–if the macro results are the thing the architect primarily cares about? In other words, why the attention to micro details (some of which are not even pragmatically necessary) if the "infinitesimal" is of little meaning in the cosmic theater?

without those microscopic details (neurons firing in your brain) you don’t get the macro results
So the infinitesimal details of existence do matter? If for nothing else than for the macro *results*? And if all of existence is oriented around such a thing as the simulation you describe, doesn't this indicate a purpose for everything, including your life?
