Is it true in 1970s, some green man-like creatures with high tech mysteriously landed on earth, then vanished? - 1970s high school yearbook

I was in elementary school in the 1970s, when the news was so strong that some sort of green digits dozen similar humanity, combined with super-powered son in one ear and fatigue, has landed the planet Earth, in the United true states of America.
Our own species Homo sapiens, scientists and security guards approached them to see who or what they really were, but scientists mysterious stranger had vanished in the air.
That's what they told us that it was forty years ago.
Please confirm to me by my e-mail if it has actually taken place.
Or do we have these things anywhere else?
