79- What is the Difference?

The Mechanism Of The Creation

What was the intention behind these human-made terms of "alive" or "dead.”? What are the differences between them? Furthermore, why do people consider these two different?
We can see that those who are alive differ from those who are dead. For instance, the live person talks, sees, breathes, thinks, moves, and carries out tasks that an alive human being does, while a dead man cannot do such tasks. Therefore, these actions differentiate an alive person from a dead individual.
If we argue that these movements and actions emerge from the corporeal body itself, how come a dead body does not do these things?
