Most stories end up being able to land on another inhabitable planet and continue our civilizations in there. But if we rewind these stories a bit:
As years past by, we continue space exploration until we have discovered another Earth like planet thousands of lightyears away. As we focus more on the said planet, we continue to discover that primitive life exists on this planet. Being very far, the current technology only allows us to just view and see what's going on in this planet. Researches indicated an impossibility to send any other investigative device on this planet due to it's distant nature, and even posted a very high expensive risk of wasting resource on a planet that might have already been destroyed by its own inhabitants.
Having discovered a planet with life in it, what are the scientific values we can gain in this discovery? (If possible, Site examples of concrete technologies that will emerge in this discovery.)
thousands: metaphor for the distance we have currently calculated to be impossible for us to reach even in a couple of millenia.
