Life on Earth (Season 1)

Life on Earth (1979) is David Attenborough's landmark natural-history series, available to watch online on iFILM. It is television's first sweeping account of how life grew from a single cell into the whole living planet.

Across thirteen episodes Attenborough traces three and a half billion years: the earliest bacteria in warm seas, plants and animals crawling onto land, then fish, insects, reptiles, birds and at last mammals. He never narrates from a studio — he explains evolution waist-deep in a swamp or pushing through rainforest. The moment he sits whispering among the mountain gorillas of Rwanda became one of the most famous scenes in television history.

This BBC production set the template every wildlife film still follows: clear storytelling, far-flung expeditions and a calm narrator who makes the complicated feel simple. It launched Attenborough's decades-long "Life" saga. Here is the strange part: footage shot more than forty years ago still plays fresher than most documentaries made today.
