We often think about life arising in one location and then spreading across the galaxy or universe. Quite interesting to consider instead life arising everywhere and then being reduced to only a few (maybe one) remaining pockets across the entire universe, or not at all. Of course that likely doesn’t apply to life as we know it, assuming our estimates of the age of the sun and the universe are correct.
