Why Space-Alien Invaders May Not Be a Big Threat

Imagine you’re an alien ship captain about to invade Earth,
and you detect all this near-Earth satellite traffic.
Would you chance it or assume that this is a planetary defense system?

I wonder if the astronomers looking for extra-terrestrial planets
hosting advanced, intelligent life are looking for a dense sphere of
satellites surrounding those planets. Seems like that would be a phase
of development that advanced technical civilizations must pass through.

(What? Well, yeah, satellites as we know ’em would be too small to detect from here,
but the thought still applies)
