AI Summary

Earth’s molten core continuously releases chemical messengers that originated when the planet formed, including hydrogen drawn from the primordial gas cloud that created the Sun. That hydrogen migrates upward through the core’s layers, eventually becoming water trapped within minerals in the mantle and crust. The article likens early Earth to a lava‑covered, gas‑spewing sphere bombarded by space rocks, then notes that over 4.5 billion years the planet has cooled enough for life to appear, yet the core still leaks these ancient materials.
