I don't think anyone would notice. How many people's attention does it take to make an event or non-event significant? (way off topic)
It was rhetorical of course. If we didn't cause changes in the Universe, or if the Universe didn't cause changes in us, we wouldn't exist.
I don't think Royce and Pit are saying that because we change the universe we are special or significant. They are saying that along with all the other components of the universe we too are involved in its evolution of change. We effect the course of the evolution of the universe and, in turn, we are affected by the same.
Saying "We change the Universe" without adding, in the same reverant tone, "So does everything else" fully implies that we're special. Otherwise, why would anyone say it?
So what you are saying is true; there is nothing significant in the fact that we cause change because everything causes change in the universe. This includes butterfly wings, a rock falling on an ant, and one gene that eventually and "significantly", produced 6,000,000,000 Homosapiens.
At first glance, six billion is an impressive number. It's a lot more than the number of wombats in the world, that's for sure. But compared to bacteria, it's hardly something to be proud of. Each one of us has trillions of bacteria eating, excreting waste, reproducing and dying in and on our bodies. Multiply those trillions by six billion, and add the trillions and quadrillions and googillions in the rest of the world. By numbers alone, homo sapiens is pretty insignificant compared to the "lowly" bacterium.
But numbers aren't a true measure of a species, I'm sure you'd agree, so how about something more significant: survival. Bacteria perform functions for us without which we can't live. In a world without humans, bacteria would do, and have done, very well, but take bacteria away and we'd soon be extinct. Bacteria thrive in places where we wouldn't last a second, and they've lived through epochs on Earth that would have wiped us out completely. Their short life span and quick reproduction rates make bacteria, as a species, much more adaptable to sudden changes in their environment than us sluggish humans. They have an incredible advantage over us in their ability to survive as a species, and yet they aren't conscious. I'd say consciousness, in itself, isn't a prerequisite for successful existence, although it is apparently required for a species to think it's pretty hot stuff.
