The History of the Earth
The Earth, 4.5 billion years old, emerged from a nebula in the Milky Way Galaxy. Gravity led to the condensation of a rotating cloud into the Sun and planets. Over time, lumps collided, forming gas giants, rocky planets, and asteroids. The outer planets attracted hydrogen and helium, while the inner
