Ancient Earth

Today, Earth is enveloped by a thin veil of gas, a narrow band of atmosphere that protects a world covered in lush green vegetation, deep blue oceans and abundant life. But 4.5 billion years ago, Earth was a very different place; a hellscape of molten lava and barren rock, under relentless bombardment from meteors, and with no atmosphere whatsoever. So how did our familiar blue sky come to be?

700 million years ago, Earth was a giant snowball cloaked in ice from pole to pole. This global freeze threatened the survival of the earliest complex organisms. How did life manage to exist in this forbidding world? This mind-blowing documentary investigates how this catastrophe may have become a catalyst for life to evolve in creative new ways as it bounced back from the brink.

For billions of years, life teemed in the oceans of planet Earth while the land was desolate and inhospitable. So how did life make the leap to land? This documentary explores how some of the earliest life emerged and invaded a barren, rocky landscape, eventually transforming it into a verdant, green world. Once organisms escaped the oceans, they fundamentally altered the very ground they grew on.

252 million years ago, the most devastating mass extinction of all time abruptly wiped out around 90% of all species on Earth. The biggest volcanic eruptions the world had ever seen, emitted some 700 thousand cubic miles of magma and rock. The event, now called The Great Dying, came close to wiping out all life on the planet. How did the surviving organisms avoid this apocalypse?

The story of Earth can only be told because now, 4.5 billion years into its existence, a technological and self-aware animal species roams its surface. As this documentary reveals, a cataclysmic asteroid strike wiped out the dinosaurs, leading to tumultuous changing climates that allowed early primates to spread across the planet. This led the way for humanity to evolve and dominate the Earth.
