A distinction between them was made in my 4th grade science class.

Again, a matter of definitions.

Depending on how you think of it, you can make a case for all three:

1. People are living things. A dead person is a dead thing.
2. People are living things. When a person ceases to be a person, it becomes a non-living pile of molecules
3. People are living things. When a person ceases to be a person, it becomes a new living thing, a heap of decomposing organic material



>hmmmm so, the person, or soul, if you will, who occupied in the body is dead, but the body was never really alive. It's just a pile of chemicals.


You can define it that way too.

That doesn't mean you should define it that way, but you could.
