OK, let’s get the juices of thought flowing.  Think about this.  

 

In the 1800’s the French lifted off the surface of the earth with hot air balloons, as did Union artillery spotters during the American Civil War.  On December 17, 1903 the Wright Brothers initiated heavier than air flight and we have never turned back. 

  

Until those events took place, human beings were 2-Dimensional beings.  We could travel in the x,y coordinates of space (east, west, north and south and combinations thereof) but we were limited to the surface of the Earth.  That is if we wanted to live to tell about it. 

  

Since that time, for, oh, about 100 to 150 years depending on whether you like hot air or heavier than air, we have become ever more agile 3-dimensional beings.  We now travel in the z coordinate of space with confidence that would have completely puzzled the Pharaohs, Cleopatra, Alexander the Great, the Caesars, Napoleon and Queen Victoria!  And of course that was completely beyond their reach regardless of their power and wealth.  We fly above the surface of the Earth without giving it much thought.   

    

Caesar was just a simple little 2-D creature, while you and all humans living today are 3-D people.  Even Thomas Jefferson was a 2-Dimensional person.  Of course Hitler was a 3-Dimensional person.  And …

 

We and our last few generations are unique in all of recorded human history. 

 

Ever stop to think about that?
