Is Earth the only living planet

I have not seen any alien in my real life but i have seen them in t.v and if anyday i see them i will inform you about it.

We're most likely not alone in this universe. But the universe is such a humongous, unconceivably big place, that it is (unfortunately) also very likely that we'll never have the chance to make contact with any other forms of life that might be out there. Not for a few lifetimes at least, until we devise good ways of interstellar travel.

hey i strongly believe that there might be some life somewhere,not exactly in our own solar system, but may be for some other solar system which has planets ,who knows there might be favorable conditions for a planet for life in that solar system, but it will be very intersting to think of how they really look like, isn't it..just imagine..and try to describe how aliens will look like and describe here....

I think it's totally possible there is life on other planets. I don't worry much whether there is or not because in either case it would be mind blowing. As far as humans and parallel Earths there are theories and it's great science fiction for now.
