That said, I do agree that the issue he is trying to point out is of vital importance. The fact is that most of the people that believe in mysticism, religions, UFOs, psychic powers, and other things to that effect are completely disconnected from the physical reality that they inhabit. However, I do not think the solution is to tell these people that their views are ridiculous, before quoting scientific facts the implications of which you might not even understand yourself. You would be better off establishing a rapport, and gradually introducing more and more facts that do not agree with their interpretation of the world. In the end you may both find some wisdom in the result.
