Aliens??
Maybe someone just found a neat looking rock, and made some stuff out of it?
I’m not saying it’s aliens, but...
Any reference to aliens would have been meant as humor. Extraterrestrial just means it originated not on Earth.
its funny, I was replying to number 1 and aborted the post because I didnt think anyone would catch my drift!!... I was going to say is anyone who was familiar with what they actually used, melted down for whatever purpose, could have very easily been walking along, minding their own business, kicked a rock and hurt their toe realizing that rock was heavier, denser than most, and knew it was metalic...
