The Indus Valley was the most advanced of the old civilizations. I daresay it was better than Mesopotamia, Egypt, Greece, China, Turkey, Japan, Tibet, the Mongols, and even the bloody Romans. I think it was even superior to 17th and 18th-century England (the Indus Valley had toilets). It should be a civilization to be remembered for all time and history.
