Reflection For Indus Valley Civilisation

The Indus Valley Civilisation began in 2500BCE.Indus Valley is a well planned city by an efficient government.It has shelter against foreign enemies, a complex drainage system and food stored for future consumption.The Indus people worked as priests who carry out religious rituals,craftsmen who create potteries and bronze tools(used for hunting),farmers who produces food and traders who sell as well as purchase products from other regions.Archaeologist found seals that indicated that the people there had a uniform writing system and they used seals for trade.
I think that the Indus Valley people are independent and capable as they hunt animals and plant crops for their survival.Indus valley is a very planned city and they are always ready for enemies' arrival as they have a sheltering place which is the citadel when enemies attacked.
