The oldest sign of life / Discovering the 3.5 billion-year-old microbes fossil

According to Mikrofon news agency (MHA), a stone has been discovered in west of Australia that is said the fossil of the microbes inside is belongs to 3.5 billion years ago, Independent reports.

Scientists believe the fossil of microbes inside the stone is one of the oldest signs of life on the earth so far.

Some critics claim that what is called “germicidal fossil” and is not visible with the naked eye are actually rock molecules that have been transformed over time, but scientists say that studies over the carbon isotopes in the rock proves Their structure is similar to the structure of the germs.

Scientists have succeeded to identify 11 types of different microbes in the stone which some of them are extinct while some other are still found in the nature.  The discovery of the fossils show that life has begun much earlier on the earth than what was thought before.
