If intelligent life was traveling across the cosmos to watch us, I think they'd be bending space and time or traveling inter-dimensionally or some other method that's beyond our understanding. I don't think they'd be driving space ships that are so close to our own way of thinking on how space ships should operate, so I think it would have to be humans that are operating these vessels in some way.

I find the intriguing part of UFOs is trying to understand what group has gained access to technology that's so far beyond what's available to the rest of us, and if this technology is legitimate or just a fancy illusion.
