Alien Encounters Writing Prompts

Mark Zuckerberg and Elon Musk are two robots sent to Earth by aliens, one sent to advance humanity, the other sent to hinder it.

The zombie apocalypse has come and gone. Humanity has survived and prospered, but with the virus still inside every single human. Centuries in the future, we are at war with an alien race, and they are horrified to learn that we don’t stay dead easily.

An entire office block is populated by aliens disguised as humans on a mission to study our behaviour. None of them are aware of each other and think they are the only alien there. As a result they are amazed that human behaviour is so similar to their own. Then a real human gets a job there.

Turns out, Earth is actually unique in the fact that nearly all of it's natural features, like quicksand, and processes, like earthquakes, can kill you. Most other planets dont do that. So when aliens invade, 90% of the fighting is done by Earth.

Aliens have realized humans advance more quickly during times of conflict, and have tried to push humanity into wars to see what happens. However, that changes when they start WW2 and humans harness the power of the atom.

Log 2543: We have landed on the planet known as Earth and have made contact with an inhabitant. They call themselves “Benjamin” and are 5 Earth cycles in age. He wished to engage in an activity known as “hide and seek”. We cannot find him now. Requesting aid.

The Reapers come every 50 thousand years to wipe out organic life that has reached the stars however this time, this time they arrive at the heaviest resistance they have every encountered. In the grim darkness of the future they find 40k.

Earth only has seasons because it’s tilted on its axis. An alien race from a planet without seasons lands on earth and begins their invasion. What they don’t realize is they’ve just landed in Russia, and winter is coming.

Turns out Humans are tiny compared to any other species of aliens, allowing them to live off in the nooks and crannies of alien spaceships. Colonies can live on ships for generations unseen and unknown, or have a mutually beneficial relationship with a crew.

FTL travel is very expensive, so humanity creates a web of hyperlanes between systems, that speed up time inside them, making travel cheaper. You enter a malfunctioning hyperlane. When you leave it, you find a galaxy with no humans, full of alien races, that see your kind as ancient precursors.

In most of the galaxy wars are often just shows of strength with fighting as a last resort. As such weapons are designed to be elaborate and flashy. Turns out humans, whose weapons are built with efficiency in mind, have a different understanding of war.

Humanity makes first contact with an alien species who are studying the life of the galaxy. When they ask to hear about our religions we offhandedly mention the church of the Flying Spaghetti Monster as a joke and they reply by saying “no, we want to know your myths not your science.”

The galaxy is actually full of life and advanced civilizations. Everyone just leaves Earth alone because that's where The Great Old Ones are imprisoned, and nobody wants to wake them up.

Humans are reverse Kryptonians. They are weak on their home planet but strong everywhere else. No one knew this until Earth was attacked and humanity was taken off of earth to be enslaved.

Long after humans found other sentient races, aliens begin to research the history of humanity. They do not realize humans write fictional stories along with history books, and they are understandably terrified.

There's a tiny predator in the human quarters that nobody is allowed to exterminate - under the threat of complete human riot. The humans willingly admit that yes, it DOES sometimes try to attack humans as well, but altogether, they are relaxed by the presence of the "cat".

Humanity has been eradicated. As the alien race that killed us begins to settle they're shocked to discover that old Earth myths of spirits and demons are far from fiction. The Devil, pissed off at the aliens, has decided to open the gates of Hell and let humanity get its revenge.

A massive Imperial fleet, led by Darth Vader, suddenly appears on Earth. Vader informs the Earth's governments that he is looking for a rogue Jedi named "George Lucas." It turns out that Star Wars is real, and Lucas has been leaking information about the Empire and the Rebellion to the public.

We may not be the strongest, but our immune systems are legendary among alien races. There is a saying: "if it makes a human sick it will kill you."

You were born with an odd power that lets you know when somebody is lying. One day you're hanging out with your friend when you turn to look at him. "Why do you look at me like that? I'm not an alien", he says. He's lying.

Humans are the deadliest, and rarest, species in the known universe. Often, search parties go missing due to a singular encounter with a human ship. It has recently come to light that there is an entire planet full of them.

Aliens don't invade earth for our resources. After a civilization achieves utopia some of it's citizens get bored and fly off to other planets to enjoy primitive thrills like violence, drugs, money and fame.

Aliens have been watching humanity for thousands of years, waiting in anticipation for us to prove ourselves worthy. Today, they came down to Earth. "Congratulations, you saw your first black hole. Welcome to Kindergarten."

We are due for a visit by two alien races, one which is horrifically brutal and sees us as soft-hearted weaklings, the other peaceful pacifists who see us as barbarians. You've been ordered to impress them, but when the ships lands you realize you have no idea which race this is.

Music is a dangerous weapon, if not careful entire species can fall to madness upon discovering it. It has been theorised that any race with more than a thousand songs could wipe out all intelligent life, which is why Humanity is so feared in the galaxy despite no human really ever knowing why

After a period where Lizard People, Aliens, Shapeshifters, Werewolves, Vampires, Guardian Angels, Cyborgs and the like were all outed as hiding as humans, it’s realized that, between all the hidden races acting like people, there are no actual humans left on earth.

Humans are the most social creatures in the galaxy, even the most socially inept human is far more confident in social situations than any other alien. The Intergalactic society finally gathered the confidence to make first contact.

At the age of 18, every person develops a magical power. Yours is the power to fluently read and speak every language in the universe. At first you thought the had the worst power on earth, that was until you you realise that the universe has it's own language.

After WW3 and a century of rebuilding, the world has been at peace for 300 years. We've let go of our violent and aggressive tendencies and abolished war. You are the leader of an alien invasion that sees the Earth as an easy target; but soon you learn we can revert to our warlike past easily.

At first, the aliens mocked our technological advancements. After learning it took only a few centuries to move from horse carriages to space ships, they suddenly became more friendly.
