People never thought of making cities and they never thought of building cities as of history…. they were quite just looking for shelters… cities are not of people … and people are not of cities…. with their unknowing birth place they just kept on coming and going ,,, thinking themselves as custodians of universe and of countries and of cities and even of the most natural place.besides they have clear understanding about departure and they realize the unpredictable future for their generations to come, on grounds of the fears of unknown and for safety of themselves ,they become the landlords ,which is may be the part of the instinct to survive and survive like lords of the forests , where smaller animals live and wait for getting eaten by the bigger ones and it goes on…..till the evolution named the jungle of millions of people the “the metropolitan” .
