Earth
as far as we know it is the only planet that has water and life
Pluto is similar to the outer planets in the following ways:They all orbit the SunThey are all ball-shapedThey all have moonsThey are all in our solar systemNone of them can support human life
Scientist are still studying. Nobody knows if there are other planets that support life.
Yes,Other planets could scientists believed some life were on other planets and signs of life

Scientists say that life can be expected to have evolved on other planets, wherever the environment is not so hostile that life can not be supported. They say that in this vast universe there must be many such planets that can support life and that some are likely to support intelligent life forms even more advanced than humans. Whether we believe that our God created the life on other planets is a matter of human faith. No doubt any intelligent life on other planets will never have heard of Earth's gods.
So far, earth is the only planet known to support life, but many scientists thing that life probably exists on other planets.
