Interesting, but I believe that investigating the possibility of life in other planets is only relevant to shed light on what has probably caused the end/extinction (or perhaps, survival) of living beings in other places of this universe. I have a less optimist perspective on space explorations than you have. If interested, I invite you to read an article I recently wrote on this topic, regarding a specific space mission that despite being ‘cool’ will probably be dreadful for humankind (https://medium.com/@MarinaTMartinez/dear-jeff-bezos-what-on-earth-are-you-doing-a7be6150b5f4).
