<b>Resolution of the f</b>_{<strong>l</strong>}<b> Variable in the Drake Equation</b>

This brief formally resolves the factor f_l in the Drake equation by demonstrating that, given an infinite set of possible worlds and an infinitesimal probability density for life emergence on any one world, the product converges to unity. Life is thus statistically inevitable, making f_l = 1. The result simplifies the Drake equation and reframes the emergence of life as a deterministic outcome of cosmic structure and infinite temporal scope, rather than probabilistic speculation.
