When a building is on fire why can it be seen from anywhere?

A building on fire can be seen from a distance due to the intense brightness and glow of the flames, which produce a significant amount of light. The flames and smoke create a stark contrast against the surrounding environment, making them highly visible. Additionally, the rising smoke can be seen from miles away, further alerting people to the fire's presence. This visibility is heightened at night, as the flames illuminate the area around them.
