Why I think the Indus Valley is the best ancient world group.

My favorite ancient world group is the Indus Valley. I like the Indus civilization  because it was  a peaceful group because they say no evidence of a war was going on with them and they also said that they didn't have guns. I  would  definitely would want to be in their group if I lived in the past. Also, I think its good to have peace because so people can work together instead of fighting all the time. Another, reason I like  the Indus Valley because they made a writing system and without them I don't think that we would learn how to write.
