It’s also unfortunately a distinctly uninformative piece of evidence about anything but space colonization and exponential expansion. All it tells us is that nothing self-replicates across the galaxy to a scale we could see in sheer infrared emissions or truly ridiculous levels of active attempts to be visible. There are so many orders of magnitude and divergent possibilities of things that could exist that we simply wouldn’t know about right now given the observations we have made.
