Life on Mars maybe possible?

Microfossils have been found in Australia show that 3.4 billion years ago bacteria lived on earth where there was no oxygen, which encourages the discovery that advocates the thesis that on Mars there may be life, the agen-cies.

Scientists at the University of Western Australia and Oxford say that the remains of microbes found in ancient sedimentary rocks, the oldest fossils ever found.

Samples were taken from the most remote regions of Western Australia, Pool Stick with places where microbes, after death, preserved in chunks of quartz.

The area has some of the oldest rock formations on Earth, from the period when almost the entire country was under water, and must have a temperature of 40 degrees Celsius.

In a study published over the weekend in the journal''Nature Earth Sciences ", team member Martin Brejzer explains that the tiny fossils preserved between quartz parts of the world's oldest bank in some of the oldest sedimentary rocks ever found.

The analysis of fossils and rocks that were found in the environment, scientists have constructed a picture of the Earth that is 3.4 billion years ago was fiercely hot and where there was a constant threat of eruption and vuklanskih meteor storms.

The sky was gray and full of clouds which made it even hotter while the sun shone less than today. Ocean temperatures were between 40 and 50 degrees Celsius.

More importantly, there is little oxygen, because there were no algae and plants to be produced by photosynthesis, he said Brejzer.

''It was a great place for us. But the bacteria was fantastic. In fact, if I were to invent a place from which life originated, the early Earth was great, "he explained.

Finally,''we have solid evidence that life existed 3.4 billion years ago. The bacteria were then and there lived without oxygen, "said Brejzer.

''Would something like that could exist on Mars? It is very unlikely, "he added.
