While I agree with you, I think, having cognition is not black and white. There are animals with great cognition skills especially among predators. Our brains are essentially anticipation machines capable of predicting the future — a trait uniquely advantageous when hunting other animals. We just happen to have specialized on this trait to the extreme (and otherwise lack good sensory organs or impressive innate weapons).

Whenever this topic comes up I have to think about this octopus who escaped an aquarium. [1]
