Language is the most exact science on Earth. It knows no imaginary concepts, nor does it recognise abstractions. If the word God exists, so must the concept behind it. Humans do not invent language – Latin-rooted invent means 'come upon', a fact screaming through languages as removed from one another as German erfinden, Russian изобретать, Lithuanian išrasti, Greek εφευρίσκω, Hungarian feltalál, Hebrew לִהַמצִיא and Turkish icat etmek. Naturally born with us to express our faith (Slavic věra, cognate with Latin veritas 'truth') in the physical Universe eloquently surrounding us, language has cumulatively been translating Mother Nature's aspects into existentially significant concepts, the only problem – thousands of years down the knowledge path – being that none of the mutually-dismissive 'believers', 'atheists' or 'agnostics' has come out with a clear definition of the 'god' they keep jealously guarding, condescendingly rejecting or cynically shunning. Outside Earth's infantile narcissism, God keeps shining, having nothing to do with our unending religious, political or economic polemics (Greek πόλεμος 'war'). Our perennially anxious Collective Unconscious keeps working hard to dislodge the planet from the orbit of the Universe – too powerful to let it succeed, too compassionate to let us lose gravity, the latter is too wise to allow our darkest side to rule over what had started as mundus 'pure' (hence French monde 'world', antonym of immonde 'obnoxious') and ended up as mundane.
God is the the spirit invoked by pouring the aromatic/ nutritive/ curative ghee oil into fire (the word is cognate with German gießen/ Dutch gieten 'pour' and French goutter 'drip'). Latin-based divine is the diurnal light and is cognate with Slavic div 'wonder'. Slavic bog 'god' denotes sufficiency – hence bogat 'rich', antonym of nebog/ ubog 'poor'. Arabic الله [Allāh], Syriac ܐܠܗܐ [Ālāhā/ Ālōhō] and Hebrew אלוהים [Elohím]) 'God' all go back to Proto-Semitic *ḥawl 'Sun', which explains why Arabic حول [ḥawl] has three meanings with no apparent connection: (1) 'around'; (2) 'year' and (3) 'power'. This makes French Dieu 'God' easily apprehensible, given the exclusively diurnal nature of the divine. The final word, however, rests with Armenian աստված [ast'vats] 'God', a contraction of Anatolian aššu-Tiwaz 'good-Sun', Tiwaz itself descending from Proto-Indo-European *dyew 'brightness', whence Latin deus, Greek Zeus and Balto-Slavic dievas – all of which denote a 'god', – leaving no doubt as to the original identity of Our Father in Heaven. The fact that Southern France's Occitan Dieu 'God' is to this day pronounced [dyew] is an enduring testimony to the long-extinct Proto-Indo-European form, speaking volumes of the major significance of 'minor' languages!
