I can only say that I don't know. The earth's biosphere is ancient and astounding.
It would be incredibly exciting to find another planet with copius liquid water let alone life.


Thankfully hydrogen and oxygen and carbon are 3 of the most common elements in the universe, the only uncommon thing is a planet that can hold them at a temperature that causes liquid water. I'm sure we will find another earth, even without life, because the universe is just so big.
