It is well known that the Drake Equation is not a serious thing. The history of it was that it was basically a conversation starter. There may be documentaries that likened it to something more solid like Standard Model, but that’s not the case. It’s a hurried back of the envelope pop-culture math-y thing that is full of vague uncertainties. We have a non-random sample of one. How can you estimate anything based on that? You can look this up; the Drake Equation is not considered something really serious, downvotes aside.
