In terms of indisputable evidence for aliens, this is one interesting branch. Unfortunately, it's a whole lot of nothing so far. 10 of 12 samples are hoaxes for sure, and 2 samples are interesting samples.
Notice the difference between this article and the hype surrounding the materials. This scientist says they can be made on earth, but doesn't understand why someone would want too.
The UFO crowd would have you believe these 2+ materials cannot be manufactured on earth.
The most obvious answer is some nerd collected some slag from a furnace and sent it to the UFO people as a joke.
This ALL hinged around the fact that supposedly, no one would WANT to manufacture these.
The totally different and not one solid mass of the same thing is the other dead giveaway that it's slag.
Does slag ever have wildly different isotope ratios like that in practice? I would guess they're pretty well mixed in the ore, without much of the kind of local variation that would throw the ratio out of whack for just one tiny sample. Unless the refining process can accidentally separate magnesium by isotopes, you need a much more involved hoax.
Plus of course there's no way to say they couldn't have been formed naturally since one can't examine all of the tiny rocks on earth to rule out it being naturally occurring.
The guy is just interpreting evidence to conform to his pet beliefs. This is not science.
It's an interesting story but it's unlikely that there is any alien machine material on our planet. Interstellar distances are unimaginably vast and there is no technology that allows for travel to neighboring stars. Even if we found "material", it's still composed of elements that are the same for all locations in the cosmos. There are no special elements per se. Chemistry and nucleosynthesis is the same everywhere. I can't rule out unusual isotopes of elements, that is true. So it would be hard to say something came from another star system.
