The Earth Peace Flag
There are all sorts of flags that appear in Contact 1997 when the public becomes aware of an extraterrestrial intelligence.
Something of a wild circus-super bowl-phish concert forms as people swarm to the locale of where the signal was first detected in Socorro County, New Mexico.
The Contact Peace Flag uses several colours - white, black, red, yellow, blue, and green. Centered on a white background was the planet earth. In the crest position it is written "Earth Flag." Across the middle it is word 'peace' in all power case letters. Each letter is a different colour with its own background panel. In the compartment position are other words written in black that are unintelligible.
This film professionally presents a sequence of events showing the cascade of events Earth would go through if it were to make hard scientific contact with a civilization outside of our solar system. At the moment there is no hard scientific evidence, but it'd certainly be a waste of space if it's just us.
And if other extraterrestrial life were to exist in a similar form and at a similar stage of development with semi-harmonious nations states, I believe that the various vexilloids of their planet would align like my fraternal flag twin idea.
Is there anyone in these universe that gets me?
