To think it was all made just for us is hubris.
Exactly and very interesting.
That kind of thinking is synonymous with the notion that the Earth is the center of the universe. But as science seems to have shown, the Earth is not the center of the universe and life wouldn't be "as we know it" if the physical laws of the universe were ever so slightly tweaked in one way or another. If that was the case, "we" wouldn't be here to ponder this.
Here's a random thought: Maybe the physical laws of the universe we think we know are different outside of the heliosheath of our solar system. How will we really know unless we get there and do some scientific testing?
