This is the opposite outcome of one of my friends advisors. We went to the Roswell UFO museum as a lark. And one of the info panels said "this is potential alien metal panels, analyzed by a scientist, Dr. So and So" and we told the professor, who got really angry. "I said that I would look at what they had and it was all flattened pieces of beer cans, I told them not to associate me with this nonsense!"
So you're saying he did analyze the metals, and that he couldn't conclusively prove that they weren't alien metal?
This whole "it's comprised of an unknown element" thing that sci-fi likes to do is ridiculous in and of itself.
If aliens did turn up on Earth their starships would be constructed out of known materials, sure it might be some exotic alloy, or other engineered metamaterial, but we definitely understand what it was.
There's no such thing as alien atoms. Iron is iron.
I'm still not convinced alien technologies would be totally incomprehensible to us. Some of it obviously will, but their tech will still adhere to basic fundamentals like levers, inclined planes, and wheels -- as well as fundamental forces like electromagnetism, kinetic energy, and pressure.
When you need to fasten two parts of machinery together, there are a limited number of efficient ways to do it. I fully expect bolts, nuts, and washers to be a universal technology. Same with focusing radiation; there are not many substitutes for lenses, mirrors, and lasers. When you need to move something around in gravity well, you're always going to need a wheel. If something needs to rotate, there aren't many substitutes for a rotor, stator, copper windings, and electricity. Gears, chains, and belts work just fine for transferring that rotational energy. Nobody is gonna go looking for exotic forces to perform tasks that can be far more easily accomplished conventionally.
