Witness Account

I was helping my parents move. It was about 6:15 PM at the time when all of a sudden, I saw a strange color-changing light from behind a tree. It let out this sound that kinda sounded like a crow mixed with a robot as it moved erratically. tried explaining what I saw to my parents, but they just thought it was a bat. I tried explaining what I saw to some people online, but they thought it was just a drone. I, on the other hand, am not so sure.
