It's a human. What's the name of this movie?

It was most likely due to the movie "Arrival." The male lead was a philologist who was responsible for communicating with extraterrestrial creatures and repairing some military equipment. In the end, it was discovered that the aliens were actually here to deliver important information, not to invade. "The Three-Body Problem" was also a novel about Earth facing an alien invasion. The difference was that this alien civilization was extremely powerful, and humans discovered their own problems in the process of finding solutions. It was a classic book that pondered the significance of human civilization and the universe. I hope you like this fairy's recommendation. Muah ~😗
