You can start by creating unique alien species with distinct physical features like multiple eyes or tentacles. Then, think about their planet's environment, like a gas - filled world or one with extreme temperatures. This can shape their culture and technology.
One possible alien origin story could be that they evolved on a planet far from Earth. Maybe on a gas giant's moon. Their planet had unique conditions, like extreme heat or different types of radiation. These conditions led to the development of different biological processes compared to life on Earth. Their evolution might have been driven by the need to adapt to scarce resources or a constantly changing environment.
Well, in the Prometheus story, the origin of the aliens is tied to the Engineers. The Engineers were highly advanced beings. They visited Earth long ago and left their genetic material, which some believe was the start of life on our planet. But they also had a darker side. Their experiments with the black goo were a big part of the alien origin. This goo could transform living organisms in extreme ways. For example, when it infected a human, it could cause a grotesque transformation. And over time, through these mutagenic processes, the aliens as we recognize them in the Alien movies came into existence. It was a combination of the Engineers' actions, their technology, and the unpredictable nature of the black goo that led to the creation of these fearsome extraterrestrial entities.
It depends on what specific 'alien origin true story' you are referring to. There are many so - called alien origin stories out there, but most lack conclusive scientific evidence. Some are just unfounded rumors or science - fiction - inspired tales.
Since I'm not familiar with a specific 'alien corn' story, the origin could be from a creative writer's imagination. A writer might have been inspired by the idea of genetic mutations in plants and decided to take it to an extreme with the concept of 'alien corn'.
One idea could be that the aliens originated from a planet made entirely of crystals. Their bodies are crystalline in nature, and their technology is based on harnessing the power of the crystals. Another idea is that they come from a binary star system, which has led to them having a unique day - night cycle and a very different perception of time.
The key elements include the Engineers' role as creators. They had the power to seed life, but also to create destruction. The black goo is central as it has the ability to mutate any life form it comes into contact with. Also, the Prometheus ship's journey and the scientists' investigations play a part. They discover the Engineers' facilities and start to piece together the origin of the aliens. Their curiosity and the actions they take on that alien planet are what drive the story forward and reveal more about how the aliens came to be.
One example could be the origin story of Superman. He is an alien from Krypton. His planet was on the verge of destruction. His parents sent him to Earth in a small spaceship as a baby. On Earth, he was empowered by our yellow sun, which gave him super strength, speed, and the ability to fly among other powers. He then decided to use these powers to protect the people of Earth, becoming a great superhero in the comic world.
Unique environments are an interesting element. For example, if the aliens come from a planet that is mostly water but has extreme pressures, like Europa. Their evolution would be shaped by the need to survive in those deep, dark waters. Another interesting part could be their method of reproduction. Maybe they reproduce by splitting like some bacteria on Earth, but in a more complex and intelligent way.
