A team of researchers from the University of Toronto has discovered the oldest water on the earth. It may help scientists to know about the possibility of life on Mars. The sample of the water was secured from beneath the Earth\u2019s surface at a base metal mine in Timmins, Ontario in 2009. The team which discovered the sample of the oldest water was led by Professor Barbara Sherwood Lollar. Researchers who conducted tests at the University of Oxford discovered the mean age of the water sample was 1.6 billion years old. This discovery might answer one of humanity\u2019s biggest questions, i.e., \u201ccould there be life on other planters?\u201d \u201cThis water is full of all kinds of dissolved elements, dissolved chemicals and it\u2019s those chemicals that allow life to eke out an existence in these deep, dark places,\u201d Sherwood Lollar said.
