Humans were also unaware of numbers and counting until we discovered/invented them in antiquity. We may be unaware of limitations that we have now, but we seem to be in a unique position in the animal kingdom to be able to overcome those conceptual limitations once a need for those concepts is identified.

I wouldn’t say humans are unique, My Labrador didn’t understand the concept of a handshake until she realised treats were available :)
