The Sun Is Not Burning Like a Campfire
Its energy source makes a star fundamentally different from a flame in your backyard.
A campfire needs fuel and oxygen for combustion. The Sun shines through a different process, which is why the ordinary image of a giant fireball can mislead.
Start at the core
NASA's Sun facts describe nuclear fusion in the core, where hydrogen is transformed into helium and energy is released. The Sun is made of plasma, not a pile of logs undergoing familiar chemical burning.

That distinction matters because the processes operate on different scales and under different conditions. A flame on Earth can illustrate brightness or heat, but it cannot serve as a literal model of how a star powers itself.
Keep the useful metaphor, lose the wrong mechanism
When a story says the Sun is fiery, understand it as a description of appearance. When it asks where the energy comes from, switch to the physical explanation. Everyday language is convenient until it quietly supplies a false cause.
The next time sunlight warms a wall, consider the chain behind that ordinary sensation: energy generated in a stellar interior eventually reaches Earth. You do not need an exotic-looking destination to encounter astronomy. A patch of daylight is already evidence of a process radically different from a flame.
