It is certain ... that the Rigveda offers no assistance in determining the mode in which the Vedic Aryans entered India., .. If, as may be the case, the Aryan invaders of India entered by the western passes of the Hindu Kush and proceeded thence through the Punjab to the east, still that advance is not reflected in the Rigveda, the bulk at least of which seems to have been composed rather in the country round the Sarasvati river, south of the modern Ambala.

Indeed, if one accepts that the migrations of Indo-Aryan speakers into South Asia already entered the realm of mythology at the time of the Rgvedic hymns, and that the latter were composed from ca. the 15th century B.C. onwards, the chronology suggested by the archaeological evidence already makes perfect sense.

If the forefathers of the Vedic Aryans were still in Cappadocia in the 14th century BC on their march towards India, there would be no time left for them to forget all their previous history before giving the final form to the Rigvedic hymns not later than 1000 BC.

In at least three passages of the Rigveda mentioning the Sarasvatī, a river corresponding to the present Sarsuti and Ghaggar is meant. For this we have conclusive evidence in the famous hymn, the ‘Praise of the rivers’ (Nadistuti) which, with a precision unfortunately quite exceptional in Vedic texts, enumerates the Sarasvati correctly between the Yamuna (Jumna) in the east and the Sutudri or Sutlej in the west... ‘of old sites on its banks’ would ‘be helpful to the student of early Indian history, still so much obscured by the want of reliable records and the inadequacy of archaeological evidence.’

This putative “Aryan invasion” was dated ca. 1500 bce, and the composition of the hymns of the Ṛgveda was fixed between 1400 and 1200 bce. The Aryan invasion theory was conceived on pure speculation on the basis of comparative philology, without any archaeological or literary evidence to support it. It was resisted as unfounded by some scholars from the very beginning. In the light of recent archaeological finds, it has become less and less tenable. Nevertheless, the Aryan invasion theory, recently downgraded to an Aryan migration theory, is still widely defended and forms part of many standard histories of Hinduism.

Since the SarasvatI, which dries up progressively after the mid 2nd millennium BC is still described as a mighty river in the Rigveda, the earliest hymns in the latter must have been composed by C.1500 BC. (p. 98)

Between the arrival of the Aryans ... and the formation of the oldest hymns of the Rigveda a much longer period must have elapsed than is normally thought.

I start with some literary evidence. RV 4.1.13 & 4. 2.16 the Angirases declare that their ancestors made sacrifices “here” atra, ie in Saptasindhu. 3.53.11 Sudās fought enemies prāk ‘east’, apāk ‘west’ and udāk ‘north’ only, but not south. So we have no Indoaryans coming from the north and driving natives southward. The movement here is from east westward (apāk) and from south northword (udāk)! M6.61.9,12: Sarasvatī, the Rivergoddess, spread all five tribes beyond the other seven sister-rivers as the sun spreads out the days – again, days and sunlight from the east! 7.6.3 Agni turned the unholy Dasyus from east to west –pūrvaś cakāra áparām! Notice – NOT SOUTH (avāk or nyāk).

Wheeler (1968, 3rd edition) proposed the following: It is, simply, this. Sometime during the second millennium B.C. – the middle of the millennium has been suggested, without serious support – Aryan-speaking peoples invaded the Land of Seven Rivers, the Punjab and its neighboring region. It has long been accepted that the tradition of this invasion is reflected in the older hymns of the Rigveda, the composi- tion of which is attributed to the second half of the millennium. In the Rigveda, the invasion constantly assumes the form of an onslaught upon walled cities of the aborigines. For these cities, the term used is pur, meaning a “rampart,” “fort,” “stronghold.” One is called “broad” ( prithvi) and “wide” (urvi). Sometimes strongholds are referred to metaphorically as “of metal” (dyasi). “Autumnal” (saradi) forts are also named: “this may refer to the forts in that season being occupied against the Aryan attacks or against inundations caused by overflowing rivers.” Forts “with a hundred walls” (satabhuji) are mentioned. The citadel may be of stone (afmanmayi): alternatively, the use of mud-bricks is perhaps alluded to by the epithet ama (raw, unbaked); Indra, the Aryan war-god is purandara, “fort-destroyer.” He shatters “ninety forts” for his Aryan protégé, Divodasa. The same forts are doubtless referred to where in other hymns he demolishes variously ninety-nine and a hundred “ancient castles” of the aboriginal leader Sambara. In brief, he renders “forts as age consumes garment.” If we reject the identification of the fortified citadels of the Harappans with those which the Aryans destroyed, we have to assume that, in the short interval which can, at the most, have intervened between the end of the Indus civilization and the first Aryan invasions, an unidentified but formidable civilization arose in the same region and presented an extensive fortified front to the invaders. It seems better, as the evidence stands, to accept the identification and to suppose that the Harappans of the Indus valley in their decadence, in or about the seventeenth century BC, fell before the advancing Aryans in such fashion as the Vedic hymns proclaim: Aryans who nevertheless, like other rude conquerors of a later date, were not too proud to learn a little from the conquered . . . (1968: 131–2)

As far as I can see there is nothing in the Hymns of the Rig Veda which demonstrates that the Vedic-speaking population were intrusive to the area: this comes rather from a historical assumption of the "coming of the Indo-Europeans." .. Nothing implies that the Aryans were strangers there.

So far as the Rig Veda is concerned, there is not a particle of evidence suggesting the invasion of India by the Aryans from outside India... So far as the testimony of the Vedic literature is concerned, it is against the theory that the original home of the Aryans was outside India.

Witzel takes up two verses which clearly refer to eastern rivers, misinterprets them as references to the Indus, further misinterprets them as references to crossings of the Indus river from west to east, and then reconstructs an entire saga of the immigration of the Rigvedic Aryans into India on the basis of these misinterpretations. He even pinpoints the exact area “eastern Iran” from which specific immigrants, “the Bharatas and VasiSTha”110, led this historical exodus across the Indus.... Is “gross misrepresentation” an adequate word to describe this whole exercise?... His sole criterion in preparing a chronological arrangement is his own geographical grid prepared on the basis of deliberate misinterpretations of Rigvedic geography.

This is on the basis of the Aryan invasion theory according to which 'Aryans' invaded India in the early second millennium BC, and conquered it from the 'natives'. This theory is based purely on an eighteenth century linguistic proposition, and has no basis either in archaeology, or in literature, or in the racial-ethnic composition of India. What concerns us more, so far as this present volume is concerned, is the attempt to brand Hindu religious texts, on the basis of this theory, as 'invader' texts: a UNESCO publication characterises the Rigveda as 'the epic of the destruction of one of the great cultures of the ancient world.'

Does it appear that the Rigveda could be the end-product of a long process of migration in which the Indoaryans not only lost contact with the other Indo-European branches countless generations earlier in extremely distant regions, and then migrated over long periods through different areas, and finally settled down for so long a period in the area of composition of the Rigveda that even Witzel admits that “in contrast to its close relatives in Iran (Avestan, Old Persian), Vedic Sanskrit is already an Indian language”; but in which the people who composed the Rigveda were in fact not the original Indoaryans at all, but a completely new set of people who bore no racial connections at all with the original Indoaryans, and were merely the last in a long line of racial groups in a “gradual and complex” process in which the Vedic language and culture was passed from one completely different racial group to another completely different racial group like a baton in an “Aryanising” relay race from South Russia to India?
