Story summary

Research indicates Earth's formation involved a collision with a Mars-sized body, Theia, which delivered essential volatile elements for life.
A study shows proto-Earth was initially dry, losing vital elements early on.
The Theia collision likely occurred 30-100 million years after the solar system's formation, creating conditions favorable for life.
Late accretion influences the evolution and habitability of terrestrial planets.
Impacts shape planetary atmospheres and volatile element abundance, crucial for understanding habitability.
