For a really deep, smart, dive into similar ideas I recommend this video by a card-carrying astrophysics/astrobiologist David Kipping explaining his latest peer-reviewed paper on the likelihood that we are alone in the universe (using Bayesian probability theory). Prof Kipping argues that the likelihood might be much greater than what even very smart people assume.
Also a surprisingly well-produced video for being from an academic. Highly recommended.
