We only know of the elements and isotopes we have here on earth. It's not only possible, it's highly probable that additional elements and isotopes exist.
One of the key identifiers of a non-terrestrial piece of material is isotopic ratios. For instance, a piece of carbon on earth has consistent ratios of carbon-12, carbon-13 and carbon-14. Non terrestrial carbon (from say a meteorite) will have different, non-terrestrial isotopic ratios.
These confirmed materials are the result of metallurgy we do not currently possess in the non-classified world and some were obtained early enough (40's & 50's) that it's extremely unlikely that they were made with human hands (in addition to non-terrestrial isotopic ratios).
Perfect layers of bismuth bonded with magnesium layers that are a micron thick arranged like a sandwich. No known process in the non-classified world to get bismuth to bond with magnesium and have perfect micron-thick layers.
No I'm sure not, WG. I'm many years removed from high school and college, but in hindsight the most damaging thing about western education isn't what they don't teach you (although that's a serious problem),it's that they don't teach students to grow up to be critical thinkers. Quite the opposite actually.
The fact that you're here tells me they failed to prevent you from becoming a critical thinker.
How could ANY material on Earth be identified as non-terrestrial since we know all the elements in the universe, and they all exist on Earth?

We're way off in the weeds here now, though.
That's so cool. They don't teach us that in my school lol

Ok, I'm open minded enough, but I still don't see that light-speed travel is possible due to acceleration/deceleration effects on organic beings.
He must mean alloys we don’t make.
