Quoted By:
The entire premise of "our planet is nothing special" is a direct continuation of the medieval opposition of science and religion
Religion told we are the center of everything, and trying to prove that not to be the case it came into habit of scientists to by default assume that there is exactly nothing special about us, our environment, or anything else related to us
From that comes the conclusion that if we are nothing special then universe should have a lot of other life besides us, and thats seem to not be the case from observations
The answer can be as mundane as "we just so happen to be the first spontaneously formed life in all of the universe"
Or even "in our universe it just so happens that life only happens to spontaneously form once"(or for example that life is so sparce their light cones do not intersect in any meaningful way, lets say only 10^10^10^10^10 years after heat death, or never due to big rip from dark energy, or any other stuff, which makes life essentially unique to itself), since we have exactly no idea about probability of formation of life
In general it all boils down to humans assuming theres such a thing as special(like "first" or "the only one") and not special(pretty much everything else) things in the universe, and since the "we arent special" tendency is prevalent people tend to dismiss stuff that doesnt fit their idea of "non-specialness" as wrong, and from this dissonance comes the paradox
