Intelligence has developed in multiple Earth species (see crows, dolphins, etc.) Intelligence isn't what separates humans from crows. It's our ability to time bind information past our lifetime. We can use oral traditions, or write down what we have learned. And the next generation doesn't have to start from scratch. And thus you get exponential growth in knowledge. It is complex language that separates us. As a data point, it is true some crows have taught their nestlings how to use cars to crack shells to get at the tasty tidbits inside, but that learning doesn't seem to have propagated very far.
