We are built from the wheels up, not the other way around. Our bodies (to include our minds) are tool which have been constructed by our genes to decipher the energies that constitute our immediate environment. Remember that the distiction between energy and matter is an illusion. Our lives are merely the process of interpretation that occurs between the voids that exist before birth and after death. DNA is really a form of energy itself. To me that means life is energy interacting with energy. Life is non-entropy encapsulated within the boundries of the inevitable. Entropy will win. Stars die. People die.
