This is fundamentally a difference between belief and knowledge.
Between faith and reason.
If there is one thing that a good educational system should strive to achieve it should be the inculcation in the young of the ability to understand the difference. Perhaps not coincidentally some US conservatives are now arguing against teaching critical thinking in school, advocating that time be spent, instead, on teaching a willingness to accept beliefs without supporting evidence.
I once cross examined a witness, who had published some untrue accusations of corruption on the part of my client, a local politician, on this issue. I asked her if she understood that there was a difference between knowing something and believing something: her answer was: I didn't but I'm beginning to.
Unfortunately for her, she learned too late, and instead of walking away having apologized, she lost everything she owned and had to go bankrupt. Such is the fate, in the long term, for all who ignore reality in favour of their belief structure. Of course, if millions or billions share your delusions, that fate will be a long time coming
