I am not anything close to an ecologist or a biologist so this question may be really dumb. But I know that water is essential. It is used in many important bodily processes and we would die without it very quickly.
So my question is, how did so many generations of humans survive without the water purification standards that we have today?
Is there a reasonable amount of dirt, toxins, bacteria, etc… that can be in water and it won’t make us sick?
I also know people have boiled water for a very long time but didn’t we only discover bacteria and viruses in the lasts several hundred years? Did people know that boiling water would purify it?
Also am I wrong for thinking that most water in nature is dangerous to drink?
Hopefully these questions make sense.

You build up an immunity of sorts to the pathogens that make you ill. When i lived in the jungle, we would drink river water and a lot of people get sick their first time but, after that you dont really get sick
