Now, I'm not the conspiracy-minded type. I'm not going to say that aliens from some other part of the galaxy detected us as an emerging threat, and so sent a probe to our planet to spray stupid juice into the atmosphere. But if aliens from some other part of the galaxy DID detect us as an emerging threat, and sent a probe to our planet to spray stupid juice into the atmosphere, wouldn't that explain, like, pretty much everything?
Honestly I've given up hope for humanity. I want us to hurry up and destroy ourselves already. Maybe those who come after will actually learn but looking at human history they won't.
