I don't know what's more unbelievable, Russia building vehicles in space or extraterrestrials.

  I know [Russia|China|SpaceX] exists and could prove it if pressed. I have no evidence that extraterrestrial aliens exist and do not know of anyone else who does either. I could not prove that they did if my life depended on it. That kinda places it in the build-by-humans camp for me. Heck it might not be a country, SpaceX builds its own rockets and that's a private corporation. Musk isn't the only sickeningly-rich person with space on their mind.

    Sure. But isn't it more likely that it would be an attribution error? I.e. the craft was actually made on earth. My point is that space borne manufacturing seems incredible. And incredibly hard to hide.

      I don't know. We haven't probed what zero-G manufacturing might be capable of. One of the amazing properties of a near-perfect vacuum is that there are near zero contaminants. Being able to more accurately control reactions might yield breakthroughs in room-temp superconductors or metallurgy. I could imagine there's some low-hanging fruit too since we're just starting to probe the possibilities. That all said, it's therefor possible that the things that make these supposed craft unique might be defined by their requirement to have been manufactured in a zero-G vacuum.
