Life is believed to have first emerged in the oceans over 3.5 billion years ago, with the earliest evidence of life found in stromatolites—layered structures created by microbial communities—primarily in places like Australia. This emergence occurred during a time when Earth was still largely covered by water, providing a suitable environment for simple, single-celled organisms to thrive. From these origins, life gradually evolved and diversified, eventually leading to the complex ecosystems we see today.
