How old are living things?
Simple life forms like bacteria have on the Earth for about 3,500,000,000 years ago (3.5 billion years). Evidence of this was found in very old rocks in Australia. The estimated age of the earth is 4.5 billion years so life originated just 1 billion years after the earth formed.
Where do some scientist believe life originated?
We have fossils, so to speak, in rocks that are about 3.5 billion years old. Some form of simple prokayote in filamentous strings. Impressions left in sedimentary rock.' Still there must have been life before this, but the evidence is implied genetics and not all that firm. Possible a form of replicator; simple genetic replication.
