If life were simple, evolution could not have created living things. Life itself, seemingly subconsciously for us, is constantly and continuously creating new habitat by making new connections and improvements to what already exists. The further evolution proceeds, the more complex the components of the effects of already existing changes become. Similarly, as we grow older, we gain experience that enables us to perform activities that would not be possible without that experience. The tragic is only that such trains of thought can never develop without the already developed progress of our civilization.
