      We do not live on another planet because there is no other planet in our solar system can support life. They are either too hot, too cold, or do not have an atmosphere we could breathe.

      The basic things that all life (we know of) needs to survive are water, sunlight, and oxygen. Most other planets we know of lack these things. You also need an atmosphere to stop the oxygen drifting off into space.

      Also for most of human history the technology didn’t exist to get to another planet!
