The Cosmic Collision That Made Earth Habitable and Gave Rise to Life
Recent research indicates that Earth formed quickly within three million years of the Solar System's birth, but was initially dry, lacking water and carbon compounds. The planet's volatile content was likely delivered later through impacts, such as the collision with Theia, which also led to the formation of the Moon. This late delivery of volatiles was crucial for making Earth habitable, highlighting the importance of impact history in planetary habitability.
