Slavs back in 6th century AD, never called them selves that way - "Slovani" (Slavs)- the term itself was invented later. They were rather known as Sklavini, Anti, Vendi, Venedi, Scynthians. Term "Slovan" was invented later, as a derivative of "Sloven". But Sloven derived from Skloven; which was a Greek and Latin fusion of 2 words; Byzantium historians understood that "Veneti" spoke similar language as Scynthians (Herodotus's Skolota; but Skolota derived from "Skot" or "skotit"; "crawl, turn around" (also a "birth"), this is a Scynthian
KOT or CAT , a sacred, royal animal and also "falcon" (Sokol). The royal symbol of almost any civilization in India, Egypt, Mesopotamia... and Europe; Norik and later Karantania ("black panther")), so they created an addition of "Skol, Skla"(Skolot; Scynthian) & Veni or Venedi; Skla-Vini, Sklaveni. Slov (word) derived from "Lob" (cutting out; from tree, wood, Lubadar (beatle) - spruce bark beetle) with betatism. So "Slov-Veni" ("speaking Veni, Venedi ").
People were speaking - "glagoliti", "govorili" (varili; "fusing together") but original "Slavs" were called in ancient times rather Bharatians (Boreans)- who influenced the artificial "Sanskrit"(Sam-Skriti). They were not "Dravidians".
Sanskrit terms as "GALA" गल (throat) (slovenian "goltanec"; throat; "goltat"; to swallow), galarandhra (गलरन्ध्र) (throat) have Bharatian / Scynthian-Venetic-Sloven-Ant origin; correct transliteration of galarandhra in Slovenian is "Glagolit"("speaking", & glas= "voice")-(ran)-dreti(screaming) ", galadvARA (गलद्वार) - "throat door" ( in slovenian as "glagolit-Dveri"), gulutagolita (note the similarity with "glagolica"; golita) गुलुगुलित- which was transliterated among Hindus as "roaring". If we transliterate whole word from Slovenian language we get; "g(o)lo(s)"(voice)-speaking" (fluidly).
From the same root derives also English "seaGUL" (note that orthodox linguists ignore the fact that GUL derives from "slavic" GALeb, sanskrit "voice", but they never figured out its correct root; derived and influenced in ancient English (Anglian) Wendic language

This is how the so called list of "Indo-European" (artificial "1. language" was born) and the transliterations (including Slavic, "satem") throught "Centum "/Kentum prism...
This is also the way how the "CAT " (KOT) was transliterated as "being germanic in origin".
Sumerian term "GILGAMESH" has among Orthodox linguists an "unknown meaning"... So they rather use Hebrew "transliterations"(instead that also "old" Hebrew derived from Akkadian & Phoenician - Artificially (written later) language, many "think" that it has an "archaic status" of the language; with few exeptions, as example Joseph Yahuda, author of the book Hebrew is Greek, a book of so called "pseudo-paranormal" linguistic (forbidden) theory.
We can now transliterate also "Gilgameš" if we know GUL or GAL; so "Galgal" (voice)-MEŠ (MIXTURE)
(Genesis 11:7)
His second name was Ziusudra(=Sumerian "Noah"; instead that both characters have more or less the almost similar story, Biblical "historians" and many historians again argue about different "story") but many orthodoxic Historians and linguists rather use Greek transliteration of the Sumerian name (not finding it in Sumerian, Akkadian itself) - so "found long life". ( Xisuthros)
But we can translate this word normally againt through Slavic and Sanskrit; Ziu - Sijoč - Sija ("Shining one") - a status of "Nagas/Nachash" (Sanskrit & Hebrew; "snake, reptilian like") ancestry (of "Anunnas, Anunaki") and Sudra/Zudra in Sanskrit as "MIXTURE" (in Slavic "sveder" - vrtat; "rotating" (mixing)).
So which language (and civilization) was the first one and dominant in Mesopotamia, Israel,...; was it Hebrew, Akkadian, Sumerian or simply "northern" "old Sanskrit" (Bharatian, Borean)
