WHEN Earth formed 4.5 billion years ago, it was a sterile ball of rock, slammed by meteorites and carpeted with erupting volcanoes. Within a billion years, it had become inhabited by microorganisms. Today, life covers every centimetre of the planet, from the highest mountains to the deepest sea.
Where is all life found on Earth?
The biosphere, by definition the place where all Earth's life dwells, is a delight with its green, wet contrast.

Where was all life first found on Earth?
The earliest direct evidence of life on Earth is from microfossils of microorganisms permineralized in 3.465-billion-year-old Australian Apex chert rocks.
