A beautiful Milky Way Galaxy background, two spaceships are opening fire.
Without atmosphere, this fighting so quiet, but is not peaceful at all, the largest way of human history, also, the first interstellar war between human race and civilization from other side of Milky Way Galaxy.
Since Soviet Union gave up dictatorships at late of 20 century, our planet into the most peaceful time. 2029, SU and US together launches the first interstellar spaceship: Earth 1, to the Proxima Centauri, to discover other life forms of the universe, also find the future for human race.
But just a little bit over the orbit of the Neptune, Earth 1 received message from alien civilization, they ask Earth 1 about information of Solar system, and how many planets has life near this area.
After contact with earth, maybe too long time human in peace, they are kind of naïve, they told everything of Solar system and even ask help from aliens, want to get better technology to helps human society.
Aliens are from almost other side of Galaxy, the first day landed on earth, immediately costs huge chaos, religion organizations first refuse aliens are real, conspiracies everywhere. After aliens friendly shows evidence of true universe works, war happened.
Firstly, life on Earth isn't from nothing, also not the god made the universe, Solar system comes just like human scientists says, natural formation. However, life seeds on earth from exile criminals on Mars, from other side of Galaxy. Those criminals live on Mars in 4 billion years ago, scientists of Mars created new life form on earth, for experiments. After Martian surface became cannot live, life on Mars are gone.
Obviously human can't accept that kind of truth, first time, religions against those aliens, but after, devout believers started to believe aliens theory, to against religions like to them for so many century's, the Pope has to say sorry to "Galileo" again.
Endless chaos are starting, without any alien's attacks, just the power of truth.
Even on Earth 1 spaceship, crews are almost scientists and engineers, they try to control they are emotions, but "Unfriend" also happens every day.
