Found this on this BBC News site. I thought it was really interesting, and thoroughly confounded any ideas of a young earth. And of course, this is how life began - as bacteria.
Scientists suggest between 60 to 70% of all bacteria live deep beneath the surface of the Earth, far from the Sun's life-giving rays.
Some of the new bacteria identified are about 16 million years old, surviving 400 metres below the sea bed.
This hostile habitat might be where life first evolved more than 3.8 billion years ago, researchers believe.
"There is evidence that life evolved in the deep sediments," co-author John Parkes, of Cardiff University, UK, told the BBC News website.
"There is clear evidence that life existed more than 3.8 billion years ago. Although, for there to be a big enough biomass for us to detect it in the rocks, it must have been evolving long before that."
But before that time, the surface of the Earth was a very hostile place, battered by space rocks and volcanic eruptions.
So, Dr Parkes thinks deep sediments may have been the kindest place for life to begin.
