People on a rooftop stare at a strange blue light

A strange blue light suddenly appears in the sky, leaving people stunned and looking up at the sky. Hossain is standing on his rooftop when a bright object swiftly descends and disappears into the distance. The next day, Hossain arrives at the scene to find a deep crater on the ground, with a shiny capsule in the center. The capsule opens, and a green-eyed alien emerges from it.
