Lets see now.....they had words for "cat" ( yep...I know what a cat is )
and a word for "dog" ( yep, know what a dog is ).
"language" is not about "words".
Interesting viewpoint. I disagree. The word is the assignment of a sound (or other abstraction) to something like a dog or a cat.
For example, I would bet that you have no 'word' for a great many phenomena that others *do* have words for because of their specialization.
