The dark, boundless universe is extremely cold and filled with various radiation rays, as well as meteors of varying sizes.
Every year, a large number of meteors, influenced by Earth's gravity, fall to Earth, but the vast majority disintegrate after entering the atmosphere, turning large stones into small ones, and small ones into nothing.
In contrast, other planets without atmospheric protection have surfaces pitted with craters.
Additionally, the atmosphere weakens the rays coming from the universe and the sun for the surface's flora and fauna, while retaining the heat brought by the sun, thus serving an insulating function.
In short,
Earth's ability to become a planet of life, where humans and various flora and fauna can thrive and reproduce, owes much to the atmosphere.
Especially the fragile adaptability of humans.
