Did Earth's Continents Come from Space?

The video explores the formation of Earth's land, focusing on the role of tectonic plates and granite. It discusses theories on how continental plates formed, including the impact of asteroids. Zircons provide evidence of Earth's early history, suggesting that impacts may have initiated continent formation. The video concludes by highlighting the need for further research to confirm these theories.
