Most readers and researchers of Hindu Religion and South Asian cultures often mention about "Aryan" and "Dravidian" groups in India. Some scholars said all groups in the Northern part of India as Aryans and those in the South as Dravidians. Some mistakenly regarded all belonging to the Upper Castes as Aryans. There is no real dividing line separating the groups as only Aryans and Dravidians. In fact, there does not seem to be a Dravidian race in any research books, only a mention of Culture, Architecture and Language styles listed as Dravidian. Germans under Adolph Hitler and Persians and some Central Asians claimed themselves to be "Aryan" race, when they had no other ancient history of a civilization to adhere to. For the sake of simplicity of understanding these terms were used in this articles to separate two distinctive cultural and ethnic groups that existed in India from ancient times though they were well mixed all over the land.

In the most ancient times, several thousands of years back, the Indian subcontinent was occupied and populated by an ancient group of aboriginal dark skinned people and traces of some of them are still said to be living in many remote areas of the land. They were the nomadic hunters belonging to the later stone age. After this period, there were agricultural groups using copper tools, domesticated animals and a distinctive cultural practice in groups with religious prayer and burial rituals noted among them. These were the original ancient "Indian Ethnic groups". There were the people with a mixture of Australoid racial features, similar to the Australian aboriginal and Indonesians, Caucasian ethnic groups like the Central Asians, Mongolians from the East and Negroid ethnic groups with African racial characters. There were also migrations from the Italian and other Mediterranean areas to the west coast, northwest and southern parts of India. The Sumerians, Greeks, Central Asians and Eastern Europeans from the West also came. They are all believed by some to be the origin of the so called "Aryan" and "Dravidian" groups.

Most of these ethnic groups mixed so much within a short period that they became indistinguishable from one another in this great ethnic and cultural melting pot. This was the time of the Indus Valley settlement. The "Dravidian" culture and religious practice were in existence before the "Aryan" influence come into this place. This is believed to be part of the Cultures of Mohenjadaro in Sind and Harappa in the West Punjab provinces of what is now Pakistan, and in parts of Rajasthan and Gujarat near the now dry "Saraswathi River" as part of the Indus Valley Civilization. There were 25 to 50 thousand people in each settlement. They used a distinct language which has defied all attempts to decipher. They do not appear to be related to the Sumerian, the Mediterranean, Brahmi or any "Indo-European" languages.

Most researches done by the scholars were incomplete and sketchy with much prejudicial and erroneous opinion. Some Scandinavian researchers attempted to decipher about 500 characters and compared this to a form of "Dravidian" script similar to Ancient Tamil. They have used a numbering system that was "Binary and Octal" in smaller numbers and "Decimal" in Higher numbers. They had large congregation halls that looked like prayer halls or bath, probably for religious practices but no Temples or Sanctums. There were evidences of streets and well-organized waterways and drainage systems. They have prayed to images very much like Siva and Parvathi and certain animal figurines. The Indian ethnic structure, from the ancient time, has been the melting pot of Caucasian, Australoid and the ancient Indian Natives and tribal races. It had some mixture of the Mediterranean, Central Asian, Negroid and Mongolian traits. Thus there was no certain "Aryan or Dravidian" racial division of the population at any time, in spite of any divisions of regional, linguistic or religious differences among them. They organized and followed a cultural and religious belief from these ancient times that was developed by their leaders and followed by all.
