Earth (2023)
Discover the astonishing four-billion-year-old story of the place we call home, told in five dramatic episodes. This eye-opening biography of Earth explores the planet's most epic moments. From the first drops of rain that transformed it into a water world until the arrival of its most incredible inhabitants, us. But humans take a back seat in this story. Instead, Earth is placed center stage. We see what happened to our world before we even emerged from the mud – including massive bombardments from space, extreme climate change, and the collision of entire continents. The series uses Planets' signature dramatic storytelling techniques to bring this unique creation story to life.
