As far as scientists know, there are no living creatures on Pluto. Pluto’s atmosphere is very thin, and not like earth’s atmosphere at all. Pltuo’s atmosphere could not support the kind of complex creatures we have here on Earth. I do believe however that there may be life forms on other planets elsewhere in the universe, and some day humans may get top meet them!

Almost certainly not. There’s an equation called the Drake equation that tries to calculate the number of other civilizations (not existence of life) in the universe. Have a look on Wikipedia.
When I was your age we wondered if we’d ever be able to know if any other sun had planets. Now we can detect lots of them

Not as we know it! Pluto is very far from the sun and so freezing cold too. But I am certainthere must be life on other planets in the universe that are more similar to earth than pluto.

Jonathan commented on :
We need to be very careful when we send spacecraft to other planets or moons. It would be easy to contaminate them with life from Earth.

There are lots of organic molecules in space. You can tell by looking at the light that reaches us from other stars. That isn’t a sign of life by itself, but it’s just what you need to get started.
