I have written on human migration in the distant past from from India,then called Bharatavarsha.
This is due to,
1. The earliest DNA has been traced to Madurai, probably not the present Madurai in Tamil Nadu, but Thenmadurai which was located in Lemuria/Kumarikandam/MU.
2. Out of Africa theory is now being discarded.
3.When one studies the history of Europe one finds that a group has been living in areas what we now call Europe had been invaded/ joined by people from the East,Asia.
The approximate time of this migrationabout 5000 years ago, fits in with the Third Great Flood in Asia recorded in Puranas and Ancient Tamil Classics.
4. What of the people living already in these areas before these immigrants moved in?
To understand this one has to remember that the landmass then was different from what it is today and Pangea and other super Continents have a clue.
Please read my articles on Rodina, Pangea.
Apart from checking these continents it is worthwhile researching the languages (present) of the people living in Europe.
When one delves deep into the ancestors and the languages spoken by them leads to Franks,Huns,Gauls,Vikings and Celts.
It is accepted that all the languages had their link to Celt.
France had the influence of Franks , a Germanic tribe and I had written earlier that Huns who preceded Franks were from Bharatavarsha.
Anglo Saxon came much later.
In all, the present Languages of Europe go back to Celt.
This leads to prehistoric period.
The time assigned to this around 1900 BC, about 5000 years ago.
This date can be pushed back based on the findings at Carnac in France and other sites in Europe.
And Celt is traced back to PIE, Pan Indo Euripean Languages.
( This is different from Indo Eurooean Languages.
This, in my opinion,is to ensure that Sanskrit does not ebter the picture.)
Celt is assigned to PIE and an ancestry of Latin is postulated while some include Sanskrit with Latin as the language the later Euripean languages sprung from.
One if he is desirous of finding facts must note that Humans had been living in Bharatavarsha during these ancient times and Vedic Sanskrit heads the Indo European Language group.
Now as the time assigned to the Rig Veda is 5000 years ago and the migration from Asia to Europe had taken place at this time, it is safe to postulate that Sanskrit is the language from which the present European languages have sprung from.
If one were to take Latin as the language from which the present European have come from one must find the origin of the people who had been speaking Latin.
And it is back to Bharatavarsha.
And one may remember Vedic Sanskrit is different from the Sanskrit which came later.
I surmise that it is later Sanskrit from which these European languages assign thenselves to.
This is du references found in the Vedas abiut the peoples who were not fron the Karmabhoomi of Bharatavarsha but from Bhigabhoomi of Milechas.
That is from area not of Bharatavarsha.
And one may note that Sanskrit Brahmi was earlier to Vedic Sanskrit and was the language of the less qualified abd they were treated as Barbarians by the Vedic people.
the present English,French,German,Romanian,Bulgarian and other languages trace their origins to Sanskrit and people from Bharatavarsha.

‘ Franks (Latin: or ) were a collection of Germanic peoples that originated in the lands between the Lower and Middle Rhine in the 3rd century AD and eventually formed a large empire dominating much of western and central Europe during the Middle Ages. The Frankish Empire ultimately led to the birth of modern France and Germany and thus the Franks are seen as the forebears of the French and German peoples (in addition to Austrians, the Dutch, Luxembourgers and some other European nations
Proto-Indo-European (PIE) is the linguistic reconstruction of the common ancestor of the Indo-European languages, the most widely spoken language family in the world. Far more work has gone into reconstructing PIE than any other proto-language, and it is by far the best understood of all proto-languages of its age. The vast majority of linguistic work during the 19th century was devoted to the reconstruction of PIE or its daughter proto-languages (e.g. Proto-Germanic), and most of the modern techniques of linguistic reconstruction such as the comparative method were developed as a result. These methods supply all of the knowledge concerning PIE since there is no written record of the language.
PIE is estimated to have been spoken as a single language from 4,500 B.C.E. to 2,500 B.C.E. during the Neolithic Age, though estimates vary by more than a thousand years. According to the prevailing Kurgan hypothesis, the original homeland of the Proto-Indo-Europeans may have been in the Pontic–Caspian steppe of Eastern Europe. The linguistic reconstruction of PIE has also provided insight into the cultureand religion of its speakers. As Proto-Indo-Europeans became isolated from each other through the Indo-European migrations, the dialects of PIE spoken by the various groups diverged by undergoing certain sound laws and shifts in morphology to transform into the known ancient and modern Indo-European languages.
