The Fermi Paradox makes me remind of https://xkcd.com/605/ https://xkcd.com/605/ . Would that extrapolation look normal for an alien or for someone of a radically different culture? Oh, even a child from our culture would argue that you just can't marry twice not each day, but for total outsiders it won't be so obvious and even some may think that it should happen. We are outsider ones in this Fermi Paradox extrapolation. We are very far from being able to do interstellar travel, specially in scale, tripulated, or thinking in some way of colonization, even for our closest star system. Like with the weddings, we are extrapolating without knowing anything about how it is really in practice interstellar travel and colonization, specially in big scale. And more than just about physics, it assumes more things about intra/inter alien culture. They must expand as much as they can, and they must do visible for everyone things (dark forest? nah), and interstellar travel/colonization is possible and desirable... those, besides the Drake equation, are the axioms of it. And they may not be true or at least give another big factor to consider in the Drake equation. Not knowing is not equal to knowing that not. You must leave space for things that you don't know that you don't know.
