Planetary collision that created moon made life possible on Earth

The video discusses a study suggesting that Earth's vital elements for life, such as carbon, nitrogen, and sulfur, likely originated from a planetary collision that also formed the moon over 4.4 billion years ago. Researchers conducted high temperature and pressure experiments to simulate these conditions, feeding the results into computer simulations to determine the size and composition of the impacting planet. The study concludes that Earth's volatiles came from a collision with a sulfur-rich embryonic planet.
