I don't speak math (one of my few regrets in life), but I am pretty sure that it is a mathematical impossibility of us to be the only planet of sentient beings.

People who read and write math can correct me and I'll take it. Just seems you can't have gazillion stars and tetragazillion planets out there, it would take some serious calculations to "prove" we are as smart as it gets. . . because that really would be depressing . . .

Drake equation.

Take the probability of all of the variables that allow a planet like Earth to host life, and multiply.

Unfortunately, with a definite sample size of one, there's disputes tp be had about which variables to include, and depending on these you either get millions of inhabited technological planets in our galaxy or 1>x>0, which we know not to be the case, as it happened once.
