In a famous Eddie Izzard bit, the comedian explains how imperialist/colonialist countries such as England stole land through “cunning use of flags.” “No flag, no country!” say the English, brandishing superior weaponry.
When the space invaders show up, you don’t want to be caught flag-less. And when you arrive on an unclaimed planet, you had better damn well have a flag to plant there before anyone else shows up. So maybe we all ought to get on board with Oskar Pernefeldt’s plan.
Pernefeldt has come up with the Flag of Planet Earth, suitable for planting on Mars or waving at interstellar soccer matches against the Na’vi.
Explanation from FlagOfPlanetEarth.com: “Centered in the flag, seven rings form a flower – a symbol of the life on Earth. The rings are linked to each other, which represents how everything on our planet, directly or indirectly, are linked. The blue field represents water which is essential for life – also as the oceans cover most of our planet’s surface. The flower’s outer rings form a circle which could be seen as a symbol of Earth as a planet and the blue surface could represent the universe.”
