Of course you are right. But I understand those people who refuse to accept new ideas. The fact is that new knowledge and new ideas are often presented as the only true ones. Although over time these ideas change and become in turn obsolete knowledge. The concept of truth becomes uncertain, and leaves a person frustrating in the chaos of ever-changing truths. Not everyone is comfortable in this chaos. While the blind faith gives a person stability and does not require to constantly change the paradigm of his world.

I often think about this question - if the blind belief somehow helps people to be happy, or take advantage of the resources of their body (what is called a placebo effect), then maybe we should not change the beliefs of such people since we have nothing yet worth of features they have with their beliefs?..

Anyway one day our descendants will laugh at us and our ideas and beliefs)))

Peace! :)
