Just so you know, absolutely none of that is true.

I don't know if the person who posted that is sincere or not, but plenty of people sincerely believe this sort of thing when it is posted on Facebook.
The annoying thing is the ancient Egyptians actually did use meteorite iron, which we know because Tutankhamun was found with a knife made from it! If you’re so interested in Egyptians using meteors to build things then the real deal is RIGHT THERE! You don’t have to make shit up!
There’s also that greenish-glass like that was theorized to have been made by a meteorite impact in the desert.
Ah yes, here we go: Libyan desert glass
Ooh I haven’t heard of this or desert glass in general before, new rabbit hole! Thanks!
Enjoy!
