Which layer is considered to have evidence of the oldest past living organism?
The layer considered to have evidence of the oldest past living organisms is the Archean Eon, specifically the rocks dating back to around 3.5 to 4 billion years ago. Fossils of stromatolites, formed by ancient microbial mats, have been found in these layers, indicating the presence of early life forms. These findings suggest that life on Earth began relatively soon after the planet's formation.
