We should not expect aliens to look anything like us. Creatures that resemble octopuses or birds or even robots are legitimate possibilities.

Key Takeaways
  • Life is incredibly diverse, spanning from microscopic organisms to skyscraper-sized trees. Alien life would be just as diverse.
  • There is little reason to believe that aliens would take on human-like forms. Perhaps an octopus- or bird-like creature is more likely.
  • Because all lifeforms want to live as long as possible, the most advanced aliens might be fully mechanized robots.
