Introductions all around- the podcast, the period of time we’ll be exploring, and the host. We’ll start by scaling Earth’s entire history down to a manageable 365 days.

We finally start the tale of Earth’s history from the beginning, in the cold depths of outer space. The Sun is born and the first asteroids assemble. When these asteroids crash into Earth today, they provide time capsules from the beginning of the solar system.

Extra credit: look for the Orion Nebula in the night sky, or go meteorite hunting with a friend.

Welcome to Season 2 of Bedrock!

This episode introduces Season 2's subject: the Eoarchean (ee-oh-ar-key-an) chapter of Earth's history. The Eoarchean lasted from 4 to 3.6 billion years ago, from February 15 to March 19 on the Earth Calendar. In future episodes, we'll meet Earth's oldest rocks, the Man in the Moon, and a faint young sun.

Since this is our first big chapter break, we'll also learn how and why geologists split time into these chapters, including one of Canada's greatest scientists: Sir William E Logan.
