As a kid we have been brought up with this thought that there might be someday that life would be possible on other planets and yes, the belief for the same still exists strong and we will be very happy if anything like this happens in the future and surely the humans will be benefited with this....
Our planet earth is a very very small part of our galaxy milky way and similiarly milky way is a very very small part of the universe...in short universe's vastness is beyond our imagination and hence it is very likey that there would be life on other planets too.
