Exploring the Origin of Our Solar System and the Precambrian Era

The video explains the nebula theory, suggesting our solar system formed from a nebula disrupted by a supernova. This led to the creation of the sun and planets, including Earth, which formed 4.6 billion years ago. The Precambrian Era, lasting nearly 4 billion years, accounts for over 85% of Earth's history. Rocks from this era can still be found in North America. Life began in the oceans with microscopic bacteria, followed by early plants and simple ocean animals like jellyfish and corals.
