Is feng shui theory true or false?

Believe is true, don't believe is false. In fact, this is a very simple question. According to natural science, the theory of geomantic omen is true or false, because from the perspective of lighting, ventilation and aerodynamics, geomantic omen can be called "pseudoscience", but from the perspective of ghosts and gods, it has no credibility. So the truth lies in people's hearts. Please believe in natural science and stay away from superstition and feudalism.
