Really? I'm wondering what then does trigger your skepticism? There's no reference points in the video, there's so much smog/clouds you can't see anything, the camera quality is bad, the only thing you see is a shadow/contour, not the object itself, etc. This could easily be a composited or rendered video.
Please, I'm genuinely interested in what it is in this video what makes you think aliens is a plausible/probable explanation?
also, UFO != Aliens. Given the size of the universe and the distances needed to travel. I doubt we'll ever see intelligent aliens in our lifetimes. or even our kids lifetime.
but its either a very good cg or something amazing.
We have satellites in space regularly scanning the whole planet. If you can see it from below you ought to be able to see it from above.
Really looking forward to having it explained. if its not CG then it's going to be a hard one to explain.
