Opinions differed. Among the answers were features such as a large brain, huge wings, and spindle-shaped bodies caused by a different gravity. There were those who did not rule out that aliens could almost look like humans. Some experts believe that if there were another intelligent civilization, life there could evolve in the same way as ours.
As one scientist put it, this is because “simple physics plus the need to compete for food and avoid predators will favor organisms with the same body structure as organisms that have thrived on Earth.”
If there is alien life on Mars, Jupiter’s moon Europa, or Saturn’s moons Enceladus or Titan, these are likely microbes.
