Civilisation in Indus Valley may predate Egypt
Research by the Archaeological Survey of India and IIT-Kharagpur has revealed that the Indus Valley civilisation is around 8,000 years old and may have predated the civilisations in Egypt and Mesopotamia. Researchers found that the Indus Valley civilisation is 2,500 years older than previously thought. Earlier research suggested that the civilisation was gradually destroyed due to climate change.
