Big man

This is Naram Sin, The Great king of Akkad, trampling his enemies...Appropriately, the Great King is depicted as a Big Man much bigger than his dead enemies...

Akkadians and their Great Kings, succeeded Sumerians as the rulers of Mesopotamia...And in Sumerian the word for "King" (see capital K) was  "Lugal" which comes from "lú" (man) + "gal" (big) and literally means a Big Man...

Now here is something "weird"...

In Serbian, the word for people is "ljudi", from Proto-Slavic *ľudьje (“people, men”)...

In Serbian, one of the words for big is "golem",  from Proto-Slavic *golěmъ...Cognate with Lithuanian "galėti" (to be able) and Lithuanian "galià"(power, might)

So coincidence that the roots are the same in Sumerian and Slavic? Again? Just like the roots for all these unimportant words:

Scribe, Tablet, Mind, Breath, Life, Grain, Teeth, Sickle

Just to be clear, Sumerian is a language isolate and has nothing to do with Slavic languages or any other Indo-European language for that matter...So what's going on here? Who borrowed all this from whom? Where? When? Or is this just an incredible coincidence...
