The deep roots of Eurasian and Indo-European languages I started my research work on the origin of Gauls and Gaulish language in 2020. My main study DID INDO-EUROPEAN LANGUAGES STEM FROM A TRANS-EURASIAN ORIGINAL LANGUAGE? AN INTERDISCIPLINARY APPROACH was published in Scientific culture in 2022 and exceeds 19,600 reads in English and French on Scientific Culture, Academia and ResearchGate . I was also invited to present my research work in a poster presentation at the World Neolithic Congress 2024, which reached more than 2,000 reads on Academia and ResearchGate. In this short paper, exceeding 10,400 reads on Academia and ResearchGate, and my Swadesh list, exceeding 4,600 reads, I will present the main conclusions of my book “Gauls from the East”, compiling my most read interdisciplinary studies about the origin of Gaulish language. I hope that this book, which approaches 23,000 reads on Academia and ResearchGate, will help readers to better apprehend my theory. My research work allowed me to establish, on the basis of linguisc, genec, archaeological, historical and religious data, that linguisc concordances between Gaulish and Slavic were linked with Neolithic migraons from North-Western India and Pakistan to Iran, Mesopotamia, Anatolia, the Caucasus, the North of the Black Sea, Danubic and Balkan Europe, Gaul and Iberia, where Neolithic farmers contributed to the formaon of the megalithic civilisaon which developed in Gaul from 5,000 BCE, and brought an archaic language stemming from an Eurasian original language. This explains the linguisc concordances I established between Gaulish, Slavic, Dravidian languages and Burushaski – 250 common words with Dravidian from 500 common words between Gaulish and Slavic (and 160 with Burushaski), as well as with Altaic, Chinese, Papuan, Uralic, Kartvelian, Anatolian and Middle-Eastern languages, and in some cases Afro-Asiac, African and Amerindian languages. Historians of the anquity, as Pliny, already menoned Dravidian migraons to the Hispanic peninsula, where Celberians lived, and French historians from the 18 th century also already pleaded for the origin of Gauls, and in parcular Cimmerians, from the Altay, the Pamir or the Hindu Kush, supported by recent archaeologic studies and, as A. de Panaguia, already advocated for linguisc concordances with Dravidian. Central Asia seems to me beer suited than the Ponc steppe as the original homeland of the Eurasian original language, as well as of Indo- European languages, taking into account linguiscs, ancient scripts, genecs, archaeology, history, religion, the spread of agriculture, the PIE vocabulary relave to the horse, the wheel and the chariot, the development of long-distance trade along the future Silk Road. The richness of mountain and river vocabulary also supports a PIE original homeland located in mountains with rivers rather than in the steppes. The Ponc steppe would be only a secondary homeland of IE languages. Several new genec studies, as Pagani at al. (2024) and Pathak et al. (2024) plead for an Out of Africa migraon to the Iranian plateau, linked with the expansion of Dravidian languages to the West (Anatolia, Europe) and to the East (Pakistan, India), on the basis of the spread of Dravidian haplogroup L1 M-22. I found lately a detailed study about the origin and the diversification of languages, “Becoming eloquent” edited by two French researchers, Francesco d’Errico and Jean-Marie Hombert, which underlines the genetic and linguistic diversity of Central Asia and the Himalayan region, in which languages belong either to the Tibeto-Burman or Indo-European family, and where there are also Austroasiatic, Dravidian, Daic and Altaic language communities settled in the mountains, foothills and periphery of the Himalayas, as well as two language isolates, Burushaski and Kusunda, pointing to a diversification of Eurasian languages in this region. According to the authors, the intricate ethnolinguistic mosaic of this region holds many keys to the peopling of the Eurasian continent as a whole. According to Cabrera (2024), Europe was peopled from Central/Southeast Asia. A recent conference dated Burushaski back to 16,000 BCE, which tends to support this theory. The numerous correspondences I recently discovered with Papuan languages (2/3 of the words of my Swadesh list) also tend to strengthen this theory. The spread of the vigesimal numeral system is parcularly significant. Talageri underlines that Dravidian and Indo-European languages are the only languages groups which share a vigesimal affected decimal numeral system. For instance, the Dravidian language Kisan has a vigesimal system. Talageri stresses that the dominant decimal system was influenced by vigesimal systems in Indian Austric languages, Burushaski, Sino-Tibetan languages such as Sikkimese, Garo and Dzongkha, and that Kartvelian languages, Basque and Celc languages have a vigesimal system. According to Telezhko (2022), Proto-Celts show a cultural affinity to the Caucasus, in parcular in the vigesimal system in Celc languages, characterisc of the majority of Caucasian languages. Traces of the vigesimal system are also present in Albanian and French, while Vasconic numeral system is wholly vigesimal, which shows the possibility of a Caucasian past of ancestors of Albanians and Basques. Celc sentences have a basic verb–subject–object typology (“Reads the son a book”), just as in Ancient Egypan, North-West Caucasian languages, Arabic, Maya, Tagalog and a number of languages of Southeast Asia islands. Moreover, Maya also has the vigesimal numeral system, this can be explained by the Altai past of the ancestors of Maya in the neighbourhood with the ancestors of Celts. To this regard, I would add Chukchi-Kamchatkan, which also shares the vigesimal numeral system with Celc and Maya and shows other astonishing concordances with Celc. According to Comrie (2013), along with the Caucasus, Papua New Guinea and West Africa, Mesoamerica has the highest concentraon of vigesimal counng systems aested cross-linguiscally. Besides that, numbers are quite similar in most Eurasian languages, pointing to a common origin. Although I am reluctant to go too far back in me about the origin of languages, first Europeans and proto-Dravidians could have a very ancient common origin, on the basis of the spread of the very ancient genec haplogroup H2 P-96 from India to Western Europe, as macrohaplogroup F, from which derived haplogroups GHIJK more than 50 kya, and in parcular haplogroup H Y-DNA, could appear in India, as well as haplogroup C Y-DNA, found in Vinča, in the Caucasus and in France, and ancient Central Asian haplogroups F, K, P, Q Y-DNA were found in Europe at significant frequencies from Serbia and Croaa to France and Great Britain, pleading for a Central Asian origin of Gauls, Celts, Slavs and Balkan peoples. I recently found a study according to which Cro-Magnon men would have come from Zagros around 50 kya. Mondal’s study also underlines chose links between Indians and Southern Europeans dang from around 38 kya, and later around 14 kya. That pleads from my point of view for a Dravidian origin of first Europeans, as Dravidian languages appeared much earlier than Indo-European languages and show affinies with Kartvelian languages and Basque, which are also believed to be very ancient languages. Although it is hard to tell with certainty which language Cro-Magnon men talked, these very ancient migraons could explain similaries established by several researchers between proto-wring signs found in many places from the Levant, Zagros, Mesopotamia, Anatolia to France from the Aurignacian (40 to 10 kya), pleading for a common original Eurasian language (see G. von Petzinger). Stuart Harris (2025) deciphered proto-wring signs of the Lascaux language, the language of Goddesses according to Maria Gimbutas, in Finnish. The queson of
