If there were a superior form of life it should have already replaced life on Earth through evolutionary competition unless Earthlife has yet to pass though some necessary precursor phase like living in the vacuum of space or downloading consiousness into machines. Other forms could of course predominate in radically different environments. This is one reason Titan is so fascinating. As a related example I think it is reasonable to assume land based life is needed for a technological civilization to develope from scratch although a transfer from a human like species to a octopus or whale like intelligent alien might be possible. In another example the movement of fish to fresh water and the development of internal skeletons there resulted in dominance of first the seas then the land and air by their descendents. The quirky/random nature of evolution is also demonstrated by the dominance of the seas by descendents of land animals (whales).
