10 Theories on What Extraterrestrials Might Look Like

Swift Summary

• Scientists have used Earth’s fossil record and evolutionary principles to envision appearances of alien life, adapting these concepts to extraterrestrial environments.
• Examples include:

1. K2-18b Life: Webb Telescope discovered dimethyl sulfide in the planet’s atmosphere, possibly indicative of life but requiring elimination of non-biological sources to confirm.
2. Jupiter’s Moons Marine Life: European Space agency’s Juice spacecraft investigates icy moons for microbial life sustained by chemosynthesis under frozen crusts (e.g., Europa).
3. alien Evolution Theories: Suggestions range from microbes dispatched via “panspermia” as existential probes to speculation that earth humans could themselves be extraterrestrial descendants.
4. Xenobiology Museum: Virtual platform imagines AI-generated alien species based on evolutionary biology guidelines and specific biome adaptations (e.g., bizarre skeletal forms).
5. Exoplanet Flora/Walking Trees Hypothesis invoking energy competition adaptation among “mobile walking trees.”
