How have humans on remote islands/atolls like Nauru or Tonga been surviving centuries without drinkable water?

What makes you think they dont have drinkable water and have been able to survive for so long ?
ELI5 – They have drinkable water
Even atolls have rain. Which collects in streams and lakes as well as creates a groundwater basin. So there is fresh water. The trope of people being stranded on a remote island traveling inn to the forest finding a waterfall and a tiny lagoon with fresh water and even fish is very real.
Rain, and also these islands sometimes have a water table you can dig too and the sand filters the water to be fresher
This sub doesn’t allow for questions with false premises. We can’t explain something that isn’t true.
They obviously have fresh drinkable water or there wouldn’t be people there.
