Anyone can find "evidence" that fits the story they already believe. This evidence is often nothing more than statistics, which is easily manipulated to "show" whatever it is you want to show. Those beliefs are based on "evidence." There are also many who believe what they are told to believe, by a priest or shaman or politician or family member etc. These are beliefs based on faith in an external source. The trick is to be able to recognize, as you are teaching your children, when the evidence might have been tampered with, by whom, and why. I do put my faith in certain entities, trusting that they have done the work, occasionally checking their show notes to see where they got their evidence. If a source does not provide their sources, and those sources are not primary sources, I do not trust their information. It's complicated! Anyone who is obviously biased is not trustworthy imo.
