NATIVE AMERICAN CARVINGS OF MYSTERIOUS GIANT HUMANOIDS DATING BACK 1,000 YEARS HAVE BEEN DISCOVERED

A scientific study has uncovered massive, ghostly figures carved into the ceiling of an Alabama cave more than 1,000 years ago.

The figures, three humanoids in shape, are among the biggest ever uncovered in the Northern Americas. Some are more than 6ft long per a study presenting the findings published in the peer-reviewed journal Antiquity on Tuesday.

Known as glyphs, the unique carvings sculpted in the soft mud on the cave's ceiling could provide clues into the traditions of Native American peoples of this southeastern US, say the study's authors.
