The Man Who asked WHY?

Once a man walking along the beach asked the first question to the world. The question was “Why?” . Now what is the story of Why?
The men of the world then were quite primitive. Language was slowly being invented. English was formed in bits and pieces. A-Z 24 letters were formed. The missing ones? “Q” and “Y”. The story about Q has been told, but this prequel is the story of “Y”.
