World's oldest fossils discovered

Pre Oxygen Sulphur life !
Now think about that and look at all the Planets and exoplanets there are in the Universe and honestly say there is no life in it other than on Earth.

Scientists say they've found the world's oldest fossils, the remains of tiny creatures that lived 3.4 billion years ago in a pre-oxygen world.

‘At last we have good solid evidence for life over 3.4 billion years ago. It confirms there were bacteria at this time, living without oxygen,’ says Professor Martin Brasier of the Department of Earth Sciences at Oxford.

The Earth was hotter than today, and dominated by volcanic activity. The oceans were as warm as a bath, and circulating currents were very strong. Land masses were small and the tidal range was huge.

And without plants or algae to photosynthesise and produce oxygen, very little oxygen was present. The early life appears to have been based on sulphur rather than oxygen for energy and growth.

"Such bacteria are still common today. Sulphur bacteria are found in smelly ditches, soil, hot springs, hydrothermal vents – anywhere where there’s little free oxygen and they can live off organic matter,’ says Brasier.

The microfossils were found in a remote part of Western Australia called Strelley Pool - the remains of the oldest beach or shoreline known on Earth - in some of the oldest sedimentary rocks that can be found anywhere.
