The oldest fossil evidence is from single-celled organisms such as bacteria and archaea. These microorganisms have been found in rocks dating back over 3.5 billion years, providing some of the earliest known evidence of life on Earth.

Bats have been on the planet for a very long time. Fossils of microbats have been found and dated back 55 million years. There are 1200 species of bats on Earth.
a fossil
Scientists can use fossils to learn about what happened about what Earth was like in the past. A fossil is any evidence A fossil is any evidence that life once existed in a place.
Fossil evidence suggests that life first evolved on Earth during the Archean Eon, around 3.8 to 2.5 billion years ago. This era saw the emergence of early single-celled organisms, such as bacteria and archaea, which were the first forms of life on our planet.
