If you are asking why do things live on other planets, the answer is because life developed there under the proper conditions. Of course, then you have to ask what is considered life, what are your ideals as to why life comes into existence, and what proof do you have that it even exists on other planets.
yes we can live
I would think exobiology is the study of living things on other planets, though we still have not found living things on other planets.
Earth, Apart from ours no other planets been proved to have living things !
Very probably
depending on the planet there cannot be living things on other planets
there might well be life but there is no live
We live on Earth, aliens live on Pluto, Mars, and other planets like Jupiter.
mars
Yes we will move planets cause we screwed our ozone layers.
We know nothing about other planets. Our best guesses are for Jupiter sized and larger. Uninhabitable, I'm afraid.
Other than the Earth, no life has been found on any of the other planets. We are still searching.
Yes there are living things on other planets. think of how many planets there are in this universe. It would be something like 1/100000000000000000000 chance of Earth being the only planet with life.
