I saw a video years ago where somebody was talking (with a translator) to a tribe, I forget where. He asked how do they count. They would point with one hand to the other hand. Once they’ve got to five they start pointing to other parts of the arm moving upwards. He then asked what if you need to count higher. They looked confused, why would they need to count higher.
For them they could exist without needing to count beyond teens.
Fun fact, for a long time in history minus (-1) did not exist
How about -2?

In the history of mathematics, -1 was understood waaaay before 0.
For the Greeks, doing 1-1 would be invalid, something close to dividing by zero for us.
Dividing by zero is well understood and sometimes even well defined.
Zero is also a relatively new invention
