No one can answer this question as we do not have any proof of whether they do or don't. Some believe that there are planets out there that are the right distance from the sun have the same size sun and planet as ours and have similar atmospheric conditions. If there are such planets, it is possible that a human or human-like species could live and thrive there.
Of the planets of our solar system, only Earth itself is easy to live on. None of the other planets are habitable without a protective sealed habitat. Of the other planets, Mars may be easiest; we'll need to build the sealed habitat, and convert some of the iron oxide in the soil to oxygen that we can breathe, but it won't be INCREDIBLY cold, or have poisonous atmosphere, or crushing pressure. And after we've figured out how to live on the Moon, Mars will be fairly straightforward.
That depends on which solar system and planet you are asking about - we now know for planets orbiting other stars.

The 3 planets closest to the sun are Mercury, Venus, and Earth. We live on one of the inner planets.
Yes we will move planets cause we screwed our ozone layers.
Because the wanted People to live. :)so we can live
Space was born with planets we don't live in like Mars, Sun, And Jupiter. It need other planets to help keep Space alive forever. It can't just have Earth.
