Why? That assumes human evolution succeeded because it's as competitive as all other animals, rather than because there is an unique level of cooperation granted by language and communication that outweighs the baser "me vs you" bits. Ants can do more than an ant because they cooperate. Efficient socialisation is what sets humans apart. If an alien society outpaces us, it's because they understand the idea of making a big thing from many cooperating small things, and replacing physical competition with abstract competition - and comprehending necessary variables impartially.
