Anything is possible
A few years ago me and my buddy were at a park around where i live and it was dark, when we were talking and a saw what i thought was a star but it looked like it was moving so we watched it for bout 15 minutes when all a sudden it came right over top us, and kept going just this huge bright light,no sound either, to this day we have no clue what it was though i suspect it was military or just a hot air balloon i have no idea but i was scared out of my mind at first and never saw it again and as far as i know nobody else saw anything that night so maybe we were just seeing things.however a few people i told said it was a ufo but i highly doubt that,i sure dont think it was but you never do know, anything is possible, but i would love to see it again and at least get a picture of it this time so people dont think i am crazy or making it up just to get attention.
