An interesting comment on Aryans and cremation

"The Vedic Aryans did come from outside India. One telling fact is the array of customs and religious culture but one such custom or rite illustrates its foreign influence. Cremation. The Indus Civilization is massively overflowing with burial grounds of their vast civilization. Nowhere, is there the indigenous habit of burning the body or its cremation. The Indian revisionists should drop their false theories before its too late." ....

Dear Juven Bachan,
 
Thanks for the comment.
 
Your thinking, the Indus Civilization remains consisting of many burial sites (at Mohenjo-daro and Harrappa etc.) as a proof of usually burying the dead in India during ancient times and the foreigners (Aryans) bringing the practice of cremation into India long ago, is seriously flawed.
 
For example, finding a number of burial sites from ancient era in a few places (Indus Valley Civilization sites … Mohenjo-daro and Harrappa, etc.) is not a  definite proof that burying the dead was a common practice among Indians (Hindus) long ago.
 
Even now, when most people living in India and belonging to the Hindu community cremate their dead, there are a few instances among Hindus (e.g. sadhus and holy men etc., with no descendents) who are buried after death (instead of being cremated).   The discovery of their few present era burial sites in India after several centuries will not be a proof that burying the dead among Hindus or most Indians in twentieth or twenty-first century was a common practice and more prevalent than the cremation.
 
Similarly, there is no country presently in the world except India (or on the Indian subcontinent), where the practice of cremating the dead is considerably more prevalent than burying the dead. Only in India and the countries with majority Hindu population (including countries where the religions branched out of Hinduism in the last 2000 years or so) the cremation is more common than burying the dead.  
 
This indicates the cremation had Hindu roots in India several millennia ago. There is no evidence to support the idea that cremation originated outside India and was brought into India long ago by the foreigners (Aryans etc.) … “Cremation and its origin in Hinduism” (http://www.geocities.ws/lamberdar/cremation.html)

Leaving aside the question of burial vs cremation, there are many factors which cumulatively support the view that the IVC people were not Aryans.
