Many species went extinct. What makes the human species so special that it needs to be preserved?
An asteroid could come tomorrow and then what?
the arrogance of the human species know no bounds.
I don't think it's arrogance to want the human race to continue. At its most fundamental, all life forms want to survive and there isn't anything wrong with that.
It took roughly 4 billion years to go from cell to civilization on earth. We, along with all of earth's plants and animals, might very well be the only life in the entire Milky Way galaxy because it is so extraordinary, the conditions having to be just right, a planet with plenty of liquid water, oxygen and hydrogen, a protective magnetic field, just the right distance from a sun, with only one moon that stabilizes earth's rotation. And then you have to avoid all the natural disasters that could wipe out life at any point anyway: the random asteroids, the volcanic eruptions, an extinction level plague. So, it's practically a miracle that we're here despite all that has likely happened over 4 billion years. I'm grateful and I hope that countless future generations of humans experience life too. I hope they reach out into the stars and go exploring.
