No , there is no proof. I think we are unique in this Universe.
There is no proof of us being unique in the universe either...
And just think about this:
There are many septillions of planets in the universe... That means that you're saying the Earth is the only planet of these 10^(21+) planets? You sure?
And then there even exists the possibility of us coming from an other planet which already contained life...

That is absolutely true, and i agree. There are so many planets out there in universe, and what are chances that we on Terra at the only ones. I will say it, its near to 0. And i guess it is ok to say that we are unique in universe, probably we are. But we are unique only as a race of humanoids, like eagle is unique in bird family. One day when we start exploring universe, we will know for sure.
