It may be possible that if there are other species we wouldnt know. When we reach one star in the sky there are millions beyond it and so on and so when we reach for a new star. I can't believe that the human race would be that greedy!

In, Fact scientists are thinking "there WAS life on Mars"

We never know if there are still dominant species somewhere on another planet or somewhere else in space.
