Sighting of a white object flying at an impossible speed.I was at my parents house in Mexico. I was just looking outside a big window on the second floor. Infront of our house like about 3 miles away there is a small like mountain or huge hill. On the right side of the mountain I see this circle white kind of gray object. Its slowly moving around. I stare for about 4 seconds and i call my mom. The suddenly it goes around the mountain to the other side and dissapears. It was super fast. It was like a white pill. It accelerated at an amazing almost impossible speed. That was all i saw. I clearly remember this moment. Everytime i tell someone they dont believe me. But other people from the same city say they have also had sightings like mine. They say long ago they saw a craft very low to the ground. it had bright lights. It then left into the sky. But i never saw that so i dont know if its true. But i know that what i saw is true.
