Hi Shaskia John,

The oldest living things still alive today are called Stromatolites (pronounced - stroh-MAT-toh-LITES). These are blue-green algae, little one-celled creatures, that live in the warm shallow ocean water along the west coast of Australia. They grow very slowly. The small mounds they for look a little like coral. Stromatolites are the most common thing scientists find amongst the Earth's oldest fossils from 3.5 million years ago.

Thanks for the great question,
