Absolutely not. I'm confident enough on that point, may be not in our solor system but there is lots of other solor system existing out there so there is chance of it for living creatures.
I have this excitement from my childhood. Are we the onlyone living in the planet called earth? Why is like that? How is it possible for only our planet? How many of you thought like me? I am confidently saying that, There are living creatures in our other planets in our solar system.
