Ummmm... couldn't it be a plane? They move can move horizontally and vertically (GASP!), they also move inhumanly fast, sometimes 2000+ KMPH. Add to that, some have lights, perhaps a large searchlight? If not, there is always rockets, a round from some experimental weapon, or a helicopter.
I believe that there must be some other life somewhere outside of the earth, but the chances that it's intelligent (never-mind smart enough to zoom around the universe at several hundred times the speed of light), seems unlikely to me.
