A time traveler from 2491 warned that aliens will first make their appearance on Earth on May 24, 2022.

"They come in peace and don't mean harm but the US attack them and begin in the first of many inter-dimensional wars. They are about 7 feet 4 inches tall and have long-shaped skulls, dark grey, and distorted appearance. They do not come to be harmful but are extremely dangerous when provoked," said the time traveler.
