| Disko Bay in Greenland |
New research found Canadian rocks that are nearly 4 billion years old with signs of primitive life. At the time, Earth was only ~200 million years old -- still a baby (in geologic terms), and who knows what the climate/atmosphere looked like back then.
Which goes to show the different kinds of (crazy hellish) environment where life started, and questions where else life may have/still exists in this universe...?
