We don't think of ourselves as a pile of atoms or molecules, we just think of ourselves as one person, even though we're made up of a trillion living cells. We're like a hive mind and every cell is an ant, each with a specific job. Does a cell have to study biology to know how to do it's job? No. And yet we have to study to begin to understand that which a cell can do naturally. It just goes to show how feeble our conscious self is when compared to the rest of our brain. We're just a node, just a viewpoint, guiding around the true intelligence. The entire history of biological evolution is written in each one of us, but we have the luxury of not being able to access it.
The little bits and pieces that make up the whole, all used to be little bits and pieces of some other whole. One day what used to belong to the arm of a king may belong to a blade of grass. But it makes no difference to the bit or piece. The illusion of death is created by a shift in the node, or viewpoint that we call life. It's like we're unable to tell the difference between creation and destruction. Or maybe there just isn't one.
