It's now generally agreed among archaeologists and historians that the Indus Valley civilization predated Aryan immigration (whether that came about by migration or invasion is a different debate). Figurines uncovered are modelled more on dravidian morphological features rather than caucasian. Linguistics experts (including Yuri Knorozov) agree that the Indus language is unrelated to Indo-european (aryan) and is close to dravidian languages - closely related to the Brahui people of Balochistan and their language - which is dravidian.
