They move across the sky all the time. I've seen many before. My best sighting was last year at the park at night when I was chilling with my friends and sitting on the swing looking at the sky to see if I can spot any weird objects moving through the sky, and I did. It was an orange light moving slowly across the sky but in a weird movement, then it flew off with a high speed. The one I am reporting now was moving across the sky, it looked close enough to be in out atmosphere. It had no blinking lights and fitted the description of a UFO. I looked at it fly across the sky. Every day and night I look in our atmosphere to see if I can spot another UFO. Please believe me as I would put my right hand on the Bible because I am telling the truth. I keep record of sightings e.g date, time, year and month and I describe it also. I would like to hear from you guys again. My friends are also witnesses as I show them where the UFO is when I see it.
