The human body doesn't consciously control whatever it is that keeps it alive. Something immensely intelligent must govern, coordinate, and direct myriad functions performed by trillions of cells (we're like a moving ant colony) and quintillions of molecular and atomic functions going on at any given second in the body.

No physical command center can be found anywhere in the body.
 
The human brain and nervous system can be thought of as a colony of worker neurons, communicator neurons, interconnecting and supporting glial cells (microglia, astrocytes, oligodendrocytes, etc.), and a variety of other specialized cells (Schwann, ependymal, satellite, etc.). The command center of the nervous system "colony" apparently lies outside of the body since no specific material locus can be identified as the leader.

​Human organs are also like colonies. There are billions of liver cells, but no identifiable controller of which liver cell will do which function, how the shape of the three pounds of liver is maintained, and what liver cell goes to which exact spot on which lobe during embryological development. The intricately coordinated mass of liver cells process about a liter of blood each minute, performs over 500 different chemical reactions, converts food to chemicals that can be used by body cells, and clears the blood of toxins—to begin the list of functions. Nobody has ever found a liver brain, nor have they explained how all the liver cells get along so well. There are no wars, insurrections, slackers, social programs, or revolutions, just harmony and peace generation after generation (unless we assault it with improper living, eating, or drugs). On top of that, if up to half of the liver is damaged, it will regenerate itself.

The lauded DNA turns out not to be some self-actuating program explaining life, but only a recipe for the use of amino acid ingredients (protein/enzyme components). DNA or other nucleic acids do not explain why all the ingredients in the trillions of creatures on Earth assemble as they do into whole functioning organisms. No physical entity has been identified that controls life's components, turns them on and off, and measures their dose. Since these machinations are far more complex than even our brains can comprehend, they are best accounted for by a super-, and supra-intelligence.
 
Brainless (actually half-witted—containing only half the genetic material of a body cell) spermatozoa swim miles (on a human scale) to find a brainless (half-witted) egg to form a fertilized whole-witted, but brainless zygote the size of this period. This in turn divides trillions of times and some of the brainless cells become livers, some tongues, some fingers, and some brains that proceed to reason that their intelligence comes from non-intelligence.

​The heart has qualities that are often ascribed to the brain, such as emotion, love, and intelligence. Dr. Gary Schwartz, at the University of Arizona, reports that there are over 70 documented cases of individuals receiving heart transplants getting far more than they bargained for. Sonny Graham received a heart from Terry Cottle who had shot himself. Sonny became infatuated with Terry's widow and married her. Twelve years later he shot himself. A young boy who wrote poetry and songs died in a car crash. His heart was donated to a girl named Danielle, who, upon hearing a song the young boy had written, immediately knew the words to it. A young boy who loved classical music died with his violin on his chest. The recipient of his heart developed a love for classical music. A lesbian who was fond of burgers received the heart of a man-crazy vegetarian lady. The recipient then developed an aversion to meat and married a man shortly after that.

​This constitutes more evidence of our holographic nature and that mind is both extraneous to and perfuses the body just like it does a flock of birds and an ant colony.
 
The idea that mind is imbued within and at the same time extraneous to our material reality has been intuitively concluded as far back as the Greek philosophers and before. Words that describe this include animism, panpsychism, enminded, and idealism. Quantum physics buttresses this by revealing that matter at its most fundamental level appears to dissolve into something akin to a timeless mind. Moreover, the design and functional complexity throughout nature infers inherent mind as do all paranormal, and preternatural phenomena.
 
Mind is not dependent on matter, but rather matter depends upon a preexistent and timeless mind. That means our physicality would have a pre-body history. That also means we would have a post-body future.
