We don't know that our intelligence is unique. Our intelligence is the collective action of individual nerve cells, each cell oblivious to the whole it creates. Likewise, the biosphere, the colletive action of all living things, may form a massive compuational engine and we would be as oblivious to it as a neuron is to us. We have no way to gauge the computational or creative prowess of other species, or of collectives of species. (No, I'm not smoking anything) If there is a God, maybe he is more concerned with the global living collective, not with us as individuals. When i speak to someone else, I could care less about the individual cells that comprise him, they could live or die for all I care. I only interact with the collective of cells that form the whole. Perhaps God cares about our wars as much as I care about the wholesale death of skin cells that goes on in a friend's body everyday. maybe individual humans mean nothing, it is only the human species as a collective intelligence that communes with God.
We also have a bias of time scale... our buildings are beautiful, but evolution created the butterfly. It took millions of years, not a few years, but who said intelligence must work on a certain time scale? The rain forest adapts over millenia, our brains can solve problems in minutes --- is faster mean smarter? Trees think slowly, but their problems evolve slowly. Again, its all relative. In our chauvinism we place emphasis on quick analysis using symbolic logic and numerical calculations, things we are good at. But there are other methods of computing and problem solving.
