Invasion

One day, like any other, you were in a restaurant having coffee while looking at your phone when a national alert popped up on the screen warning you that it was not a drill.
Cashier: Sir, we need to evacuate...now...hurry and follow me
You decide to follow the cashier who runs ahead of you to guide you to a helicopter. Behind you, you hear explosions, and you don't want to look back. As you board an evacuation helicopter, it takes off, and when you arrive at a hospital, a doctor helps a woman, her newborn son, and the father onto the helicopter. When you look to your right, you can see a huge ship firing lasers at the city, destroying buildings and houses. Along with other ships, thousands of alien vessels have arrived to invade the world. Everything seems lost until the army arrives. With their helicopters and warplanes, they fire at the ships as much as they can, destroying a few that lack energy shields. The cashier takes your face in her hands and makes you look her in the eyes to see if you're okay, and you just nod, the shock still on your face. You can see alien mechs in the streets, firing at the people who remain in the city. A ship with two laser cannons arrives in the western part of the city, reloads its cannons, and then fires, causing an explosion equivalent to half a nuclear bomb. W54, whose explosion caused the destruction of that spacecraft destroyed more than 3 kilometers along with 3 others in the north, northeast and east

For days you saw strange behavior in the clouds; most went to the right like the wind, but you always saw 3-5 clouds going in the opposite direction, and you thought it was normal. But seeing the same thing happen every 2-3 days didn't seem normal, but to you it was, until the day came and everything began in total chaos.
