Where did Pandora come from?

Pandora, an unknown alien creature, fell into a meteorite on earth. Although Pandora can purify the toxins in the air, it will grow and expand wildly after absorbing rainwater, becoming extremely aggressive and causing great harm along the way. In other words, as long as it rains, the chances of mankind defeating Pandora are even smaller, and mankind will face destruction until the resources are completely occupied and exhausted by it.
