3.5 billion years ago is the oldest direct evidence for life on Earth. Direct evidence is found in 3.5-billion-year-old cherts (rocks deposited in the ocean) in which several microorganisms have been identified. These microogranisms are much like cyanobacteria which is found in abundance throughout the Earth today. 3.8 billion years ago is the oldest indirect evidence for life on Earth. Indirect evidence is found in 3.8-billion-year-old banded iron deposits (chert) which contain a Carbon 13 to Carbon 14 ratios similar to ratios found in organisms today.
