Indian civilization around 2500 B.C.

 Around 2500 B.C., civilizations emerged in Mohenzodaro and Harafa in the basins of the Indus River. Harappa was the first place where Indus civilization was discovered. In Mohenjodaro, which means "the hill of the dead," many artifacts showing the high level of Indus civilization have been excavated.

  Mohenzodaro and Harappa are famous as planned cities. The city has paved roads, brick houses, and public baths. There is also a sewage facility, so sewage from each household's kitchen, bathroom, and toilet was flowed through a brick sewage system. Compared to less than 100 years ago, it is very surprising that Korea has sewage facilities. The people who built the Indus Civilization, like other civilizations, used bronze and letters. But I haven't figured out what that letter means yet. Among the four major civilizations, the only undecoded character was the one used by the people who created the Indus civilization.

  We don't know exactly who made these amazing cities and civilizations yet. It is clear that the ancestors of the people living in India are not Aryans. They entered India around 1500 B.C., 1,000 years after the formation of the Indus Civilization. Because the Aryans knew how to handle iron, they were able to make weapons much stronger and sharper than the Bronze Age used by the people who made the Indus civilization. The Aryans conquered India based on excellent iron weapons and slaves the people who originally lived in India. Today, scholars speculate that the Dravidans living in southern India created the Indus civilization.
