A microfossil as old as 3.4 billion years old was found to have explained how life started both on Earth and in celestial bodies above.
This ancient evidence of 'methane-cycling microbe life' which may have originated from underneath the seafloor could give insights on how or where life began how and where life first began during the Paleoarchean era, 3.2-3.6 billion years ago.
These life forms found in rich liquid made of cooler seawater from above its floor and warmer hydrothermal fluids from the below, mixed together might even tell us whether they were around long enough or much earlier than Earth's history.
