Long before the dawn of civilization, a lack of language skills prevented people from putting original ideas together and to contemplate the world around them.  For hundreds of thousands of years, actions were driven primarily by instinct.  Their sphere of thought did not go beyond their immediate needs.  When they were hungry, they searched for food.  When they were cold and wet, they looked for shelter.  Connecting one event with another or one thought with another was not possible, for without an organized language people’s thoughts were disassociated from one another, rendering them incapable of rational thinking as we know it.  Thoughts, emotions, and desires flashed in their minds like pictures on a flash card.  People could not ponder even the simplest things in life, much less their place in the universe.  But once the human mind, languages, and culture developed past a critical stage, changes came quickly.
