I was walking to the sf bay bart station in el cerrito at 4 am to go to work. it was so early there was nobody around but me. i stopped to put on my head phones and l looked up at the sky and saw a big blue orb shoot down towards me then it hovered for about 10 seconds. i have never been so scared in my life!!! and then it immediately took a 45 degree angle turn and shot back into space! im not crazy i know what i saw!!!
