月面のクレーターの調査より、誕生直後の地球にしばしば大規模な隕石の衝突があったことを示し、直径400km以上の巨大隕石の落下で起きる現象を定量的にシミュレーションして巨大隕石の衝突による地殻津波と岩石蒸気の発生と海洋蒸発の様子をCGで映像化する。その一方で、地下深くにまで生命が進出し、また、衝突による高温が容易に地下まで届かないことを示して、生命は地下で生き存えて来たと説く。

Over the ages, continents have shifted their positions, wind and rain shaping and reshaping the surface. Scientists believe that at least two total ice ages have occurred, each lasting for millions of years.

From microbes to the first complex creatures, life was always searching for new frontiers. By 450 million years ago, Earth had become a less violent planet - no longer bombarded by giant meteors from space and the great ice ages had passed.

The dinosaurs would roam the Earth and ruled for millions of years, until a disaster from space wiped them out and cleared the way for the mammals to rise and dominate the planet.

The human race is here today because of its ability to adapt. Our ancestors, the earliest mammals, survived low oxygen levels. Later primates developed sharp eyesight and hands that could clasp for nocturnal life in trees.

Earth provides a rich environment, and many factors continue to shape the planet's condition. This episode is a summary of the previous five, condensed into a single hour.
