Earth's first genesis. First life on earth Sulfur based, with genetic code older than DNA and RNA?

This is way fascinating.  Another scientific consensus could be turned on it's head.

The coolest thing to me, is the possibility that life could exist or may have existed in Enceladus and Europa or like environments that have prevalent sulfur compounds.  The  astrobiological implications are huge.

To go further.  If there were in fact two separate genesis of life on Earth.  That life arose independently twice on Earth, we can be confident that the universe is probably teeming with life.

So the idea that no carbon based life would survive due to the high UV radiation environment makes sense.   The rise of Oxygen in the atmosphere dealt with that but later on.  I have read ideas about Silicon based life but not sulfur

 Interesting

 

Even without out this, iT seem obvious to me that there is a significant amount of life in the Universe besides the Earth
