Honestly, this story is why I have a slight phobia of aliens. So bear with me here, because I was pretty young and the memory has gotten more hazy with age, though I have my dad to corroborate the story. Once when I was around 7 or 8, my father and I were on our way home late at night, and as were going down the road to get to our neighborhood, I looked to my right to the end of the road (where they were building a new school, at a construction ground). I saw a bright light hanging in the air, illuminating the ground beneath it. There was no construction going on, there was no machinery there that was holding the light, it was just floating there, minding its own business. I was the first one to see it, and I turned to my Dad unworried at first because around that age I just assumed my dad knew about everything under the sun, and that he was smartest guy around. So I asked, "Dad, what's that thing?" he turned to where I was looking, and just stared at it for a second, he said "I don't know." he turned back to facing the road and began speeding until we got home. He dropped me off and went to go see if the light was still there, when he got back to the area, the light was gone. To this day I have no loving clue what that was.
