I recommend looking up The Deathworlders for a similar feeling. Or better yet, the origin story for that from the Humanity Fuck Yeah community. I forget the exact name, but something Jenkins.
In reality, it's our best guess that a rock accidentally floated by the earth and did the damage as a random act of nature. How could we know if an alien race hurled that rock at Earth on purpose? Or even used a weapon to do it - could we tell something like that just from our geological record/proofs? I imagine we'd still conclude an accidental rock.
For this to happen, we have to assume so much. Like we are not alone in this universe and that being is aggressive. Also have the ability to move large matter.
OR.... we can just assume with things we do know that happens to other planets. That meteor happens to many planets including outs.
I think I'm picking up what you're putting down. You're saying that the universe itself knew that dinosaurs were too OP and needed to be stopped before the situation got out of hand.
Ah, context does help a bit. Still though, in almost any era of Earth, I don't see much reason for aliens to take interest in this complex planet, whether it's to inhabit it or destroy it.
If by chance there actually are any aliens out there observing us, they're probably laughing and watching us destroy ourselves..
the only thing interesting about this planet is it's life.
I've come to assume that if aliens do come here... it's either to wipe us from existence or to convert us. (and then wipe us from existence when we refuse to convert.)
But there's no way any aliens would be interested in our resources (there's much easier resources to acquire if you're space fairing,) they wouldn't be interested in territory (again, it's a lot easier to build a space station than it is to come to another star system,); trade is prohibitively expensive except for cultural exchanges (and really we've been blasting our "culture" out into space, so... uh...yeah.)
As you were told, that's not what the comic was about, but maybe the aliens breathe CO2 and methane, so they've organized a secret plot to take over the planet.
