The world is made of the smallest building blocks all over. They are atoms and molecules which are creating the vast variety of the appearances. We see a tree, which is mainly wood and water and wood contains mostly cellulose, a hydrocarbon. We see a mountain made of rock, which is mainly inorganic minerals like iron oxides or silicon oxides. We see our children laughing and do not recognize that they are water and some proteins.
But all this chemistry is creating der whole complexity and variety in life. It actually does not matter if you are chemically a rock or an animal, all that matters is that you are. Wherever, whatever! We all might have been some simple rock, plant, insect or worm at some point in existence. Who cares, we are now creative, intelligent and cultivated people.
