Man realised long ago that safety lay in numbers. Naturally, he started living in clusters. This lead to many remaining idle when some went out hunting. Fortunately, idle mind turned out to be an accidental discoverer of food cultivation, which was a refinement over food-gathering. Continuous expansion of cultivation in area, quantity, quality and variety led to civilisations sprouting up in different places, especially along rivers. These civilisations, through historical events, metamorphosed into more than 200 countries as of today.
