Fire: Earth's original reality TV show, featuring spontaneous combustion and dramatic exits! At its core, it's a rapid chemical process (let's call it an enthusiastic Oxidation reaction) releasing light and Heat. Born from Combustion, this transformative force has both nurtured and, shall we say, 'redecorated' landscapes and civilizations. It's often described as 'too hot to handle,' being both humanity's best friend (hello, cooked food!) and occasional fiery nemesis (oops, there goes the forest).
