'Earth is a cruel place. Humans are cruel. They destroy everything, kill and do experiments on beings like us. That's what we heard from our ancestors. Now we will kill every human on that planet and will live there.'
With the intention of annihilating the Earth, we unleashed our weapon, a small parasite capable of consuming human flesh in mere seconds. As anticipated, the results were catastrophic. Humans engaged in theft and violence, taking lives of both other humans and animals. What was even more frightening was the sight of humans in white dresses wielding knives, extracting internal organs from their fellow humans. Through our spying device, the parasites rapidly spread across the globe, resulting in a dramatic decrease in the population.
As the parasites prepared to execute their destructive task in a specific area, I noticed a particular human who captured my attention due to their apparent kind nature.
"It appears that there are still some decent humans out there."
Unfortunately, the parasites couldn't be stopped.
"Bring that human to our spaceship."
The fellow beings looked confused but did what I said since I was a senior. So on my command, my fellow beings abducted that human and brought it back to our spacecraft for safekeeping.
