   'Subjectivism' is kind of 'hard wired' into the human brain.   
      
   E.g. we regard as moving what we see, but cannot see ourselves moving,   
   hence treat our own body as mainly stationary.   
      
   Even if we walk, run or drive a car, we usually maintain that perspective.   
      
   'Geocentrism' is certainly more valid, but most living beings do not   
   have the faintest clue about where on Earth they actually are.
