> a highly aggressive apex species

I won't pretend that I'm some expert but I find this and similar approaches very anthropocentric, stained with pop-culture of image of aliens namely from the Independence Day and Alien (sic) series.

Why extraterrestrial life has to be aggressive at all? I'd rather imagine that if something exist out there it either have similar fears that we have or don't bother with rest of the universe and prefers an isolated existence because it already discovered that own survival is more important. And perhaps it doesn't resemble humanoids at all. Hell, maybe it even takes form of giant organisms that can freely roam through the space and just exists.

Perhaps the most boring and obvious truth is that we're alone and we exist because of sheer series of weird and improbable accidents. Pretty sure some people who work in this field believe that we're first to emerge as a sentient intelligence. So perhaps it's up to us if should reach out to the stars and explore, spread across the space. Or it might be possible that we're in a fine-tuned simulation ran by our ancestors who evolved beyond physical form and who decided to study us as we study microorganisms in a Petri dish.
