Indus valley people did not possess great palaces and temples rather the civilization was noted for its cities built of brick, roadside drainage system and multistoried houses. Indus valley people were peace loving. They were never engaged in any war. However speculations have been rife that some tectonic forces destroyed the civilization. Some historians are of the view that invasion of Aryans, sea level changes, earthquakes might have brought the civilization to its end therefore people employing horse drawn chariots in warfare is not true. Moreover, Indus valley seals show swastika, animals which is suggestive of their religious beliefs. In view of large number of figurines found in Indus valley, some scholars believe they worshipped mother goddess symbolizing fertility. They worshipped a father God who might be a progenitor of the race and was a probably a prototype of Siva as the Lord of the Animals.
