>>Oggy; please point to at least ONE original scroll or engraving anywhere, concurrent with bronze age Greece, that stated "DIAMETROS HYDROGONO"<<

Diametros is ancient and modern Hellenic for “diameter”. You don’t specifically need to find this word with anything else it existed on its own.

Now HYDROGONO is a modern Hellenic word for Hydrogen. Hydrogen was created so as to mean the offspring of water. We can thus break it up to two ancient Hellenic words:

HYDOR(water) + GONOS(offspring)

Since we are talking about the offspring of water we need to take the genitive infliction:

HYDOR(water) + GONOY(offspring)

But in pre-Eucledian non Ionic alphabets the irregular) diphthong “OY” was written as “O” thus the whole phrase is:

HYDOR + GONO = HYDROGONO

If they wanted to say offspring of water in ancient Hellas this is how they would have written it this way.

Speaking of water here is how ancient Hellenes encode water molecule dimensions and form(radius[AKTINA] and angle[GONIA]):
