Thanks to the Country of Chile for this video.

It looked like it had propellers, so I'd say it's ours. 

My main concern here is, what is it spraying in our skies?!

I don't know what it's spraying either. But I didn't see any propellers.They could have been dumping their Waste before assuming F T L (faster than light) travel.

It's hard to see them, but if you stop the video at :02 and :03 at the very beginning, you can see a shadow above the craft. 

You can't see them after that because it's too far away.  Anything with propellers has to be our primitive junk.
