The scenario you described, where a star is so close that it pinpoints a single building and leads strangers directly to it, does not have a scientific explanation within our current understanding of astronomy and physics. Stars are incredibly distant celestial objects, with the closest star to our solar system, Proxima Centauri, located about 4.24 light-years away. This means that light from Proxima Centauri takes over four years to reach us.
Stars are massive, luminous spheres of plasma that emit light and other forms of electromagnetic radiation. They are distributed throughout galaxies and exist at varying distances from us. While stars can appear as points of light in the night sky, they are too far away to have such a specific influence on a single building or to guide strangers to a particular location on Earth.
It's worth noting that ancient civilizations and cultures often attributed supernatural or mystical significance to celestial events and objects, including stars. However, from a scientific perspective, the positioning of a star relative to a building or its influence on guiding individuals is not a phenomenon that can be explained through the principles of astronomy or physics.
