Why I believe we ought to build a spacefaring civilisation

The successful launch of the Falcon Heavy is a milestone, and it has raised again the important question: should we humans try to create a spacefaring civilisation, even if we could?
 
This is a philosophical question, and answers to it are ultimately subjective. However, for those who are interested in such matters, I solved it to my own satisfaction quite some time ago. My conclusion, which obviously is a subjective one, is that we ought to at least try.
 
For all we know, we are the only tool-making, potentially spacefaring intelligence in the galactic neighborhood, possibly in our galaxy (there is a recent Bayesian estimate that suggests this might have as high as 40 percent probability) and maybe even in the visible universe, though I doubt that. Furthermore, as far as we know, complex life does not exist anywhere except on Earth.
 
Furthermore, we know for certain that cosmic disasters that are capable of wiping all complex life and possibly all life on Earth are a mathematical certainty. It’s not if they happen; it’s when they happen, and what can be done to prevent or mitigate them.
 
Normally, most people would agree that letting even one species go extinct if we could prevent it is an environmental wrongdoing, possibly even a crime.
 
What sort of crime it would be to let all life on Earth go extinct, if we had the opportunity to save at least some of it? To me, this would be a monstrous crime indeed. Even if the nearby stars teem with life, all life is unique and letting Earthlife go extinct from our neglect would be akin to letting an ecosystem on Earth die off. And if life is rare, then letting Earthlife go extinct could even mean the death of life itself.
 
This is the largest single reason why I don’t see environmental protection here on Earth and a vigorous space program as separate choices, but as complementary approaches to ensuring the longevity of life, experience and memory. The universe may not need curious creatures that are in awe of its wonders, but I still think this is a better place because such critters exist.
