Because they hold lot weight
You would find hot air balloons everywhere and some times on large fields.
There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.
Both modern and olden day hot air balloons use the same principle of heating air to create lift and ascend. They both consist of a large envelope to hold the hot air and a basket for passengers. The basic design and operation of hot air balloons have remained relatively unchanged over time.
This may not help, but I didn't think it had ANYTHING to do with hot-air balloons...
People think that hot air balloons where made for battles.

Hot air balloons float because hot air displaces cool air in the atmosphere
Hot air balloons are now mostly used for leisure
Helium-filled balloons last longer than hot air balloons. Helium is a non-flammable, inert gas that does not expand or contract with temperature changes like hot air does. Hot air balloons require periodic reheating to maintain altitude, whereas helium balloons will gradually lose lift over time but can remain buoyant for days.
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
Balloons contain helium or hot air.
