Perhaps you don't have any clue that earth and it's inhabitants are very, very likely to be the only one, - - or, of the very few planets in our known universe, with such a sequence of events over millions if not billions of years that allow us to be living beings, evolving - - while out in space is a vacuum, intense radiation, no oxygen, no food or water for many hundreds if not thousands of light years distance away. Incredibly few of our species grasps this fact and actually appreciates it ...

These people are completely useless. They would never come out of the cave or the forest. They'd sit in the village they were born in forever never knowing what is beyond the horizon. Never tasting the fruits of the universe forever content with only what they can see only to be wiped out by a random virus or errant rock from the sky. I am so so thankful for the engineers, scientists, and literally every junior dev at SpaceX right now.
