The people who lived in the Indus valley did not fight much, we did not find many weapons were they lived, peaceful people were rare but the Indus valley was one of them. The people who lived in the Indus valley used to trade, people have been trading for a really long time, longer than your life, before your great grandfather was born before, even before your great great great great great grandmother was born and that is about more than three hundred years ago, we were trading a really long time ago, we are even trading right now, some people are trading in steam, real life and in other stuff, trade was really good because you could get what you wanted and the person you traded with would get the thing he wanted but sometimes you can say this thing is really expensive and it isn't and trick someone that is bad so trading is bad and good but it is mostly good.
