Speed of Light does a pretty good job of creating a natural bubble. An advanced galactic society may have the knowledge and tech to detect patterns in solar systems that may produce life in the future and predict which star systems may have life. Is humanity even generating enough radio signals that may be even remotely possible to detect on Alpha Centauri (4.367 light years away)?
