"Oldest Water on Earth Drank by Scientists, Reveals Clue to Evolution Gap"

Scientists from the University of Toronto discovered the oldest water ever found on Earth, which was between 1.5 billion and 2.64 billion years old, and had evidence of past life. The water was found in a Canadian mine and was flowing at rates of litres per minute. Professor Barbara Sherwood Lollar, who led the team, tried the water and described it as "very salty and bitter" and "much saltier than seawater."
