Here's why:
* The Sun is a giant ball of plasma. Plasma is a state of matter where atoms are stripped of their electrons, creating a superheated, electrically charged gas.
* The Sun's "fire" is nuclear fusion. The intense heat and pressure within the Sun's core fuse hydrogen atoms together to form helium. This process releases enormous amounts of energy, which we perceive as light and heat.
* There's no solid surface. The Sun doesn't have a solid surface like Earth does. Its layers transition gradually from the dense, hot core to the thinner, cooler outer layers.
Think of the Sun as a giant, swirling, constantly changing ball of energy, not a solid object with flames.
