These fossils would challenge our fundamental understanding of the origin of life.


We would have to revisit what we thought we knew about the potential for organic matter to flourish during a time when the Earth was bombarded by asteroids, the environment was changing radically every hundred years, and the planet's surface was sodden with molten lava.


If life was able to develop under those conditions, we're left with more questions than answers.


What we believed to be a steady process that required time and caution might just be something more sporadic, which would in turn suggest that life might be more of a cosmic phenomenon than just an Earth-based one.


This could change how we think about the potential for life on other planets, or even Mars, which was teeming with oceans and warm 3.77 billion years ago. 


Not finding life on the Red Planet would tell us a lot, too, namely that life on Earth is due to some fluke or a phenomenon 'unique' to our planet.


Now, all that's left to do is wait to find out if these ancient fossils are as ancient as their discoverers hope...
