The neighbors of the upscale Carlisle Creek suburban housing addition gather outside, in their yards and along sidewalks and streets, to witness the home-shaking display taking place in the distance above them. The sky is alight with explosions that color the heavens like too many fireworks.
It had been a surprise to humanity that the hostile extra-terrestrial visitors considered the recent passage of the Voyager 2 space probe through the outer solar system a breach of their sovereign space.

I have always thought it was a bit brazen to send space probes into outer space, especially with a bit of encouragement to come find us. One person or agency’s sense of exploration could quickly lead to an extra-terrestrial annihilation of all humanity if we just so happen to meet the wrong ETs. Our own past here on earth tells us as much. Is a vigorously enforced “sovereign space” unrealistic? Our own history her eon earth suggests that it is not.
Of course, if ETs showed up en masse, I suspect many of us would stand outside and watch.
