The most creative person in the world in my opinion is Bob Marley. I think he is the most creative person in the world by bringing peace and uniting people of different races, backgrounds and nationalities with just words and music. Especially since he did this during a time where people just hated each other for no reason, the Cold War. The world was divided in two parts then and he just spread the word of peace and got many followers.
In my opinion he is more creative than other people who are really creative for inventing or turning around companies because he actually changed mind-sets instead of just changing lifestyles, perceptions of computers or other things like that.
