The Hopi Indians are cataloged by anthropologists along with other indigenous Americans such as Taos, Acoma and Zuni as Pueblo People. The pueblo people are Amerindians of the Southwest who lived / live in pueblos and practice a largely agrarian lifestyle. The Pueblo people are believed to be descended in whole or in part from an ancient ancestral group known as the Anasazi.
The Ant people led the Hopi into caves where they found refuge and food.When the Hopi food supplies ran short, the Ant people taught them methods of food preservation and storage and shared their own food with their primitive wards. Native American Legends - Tapka the Second World
This happened as per legend , not just once, but twice. At the ending of the First World which was destroyed by fire and the second which was destroyed by Ice.
There are still cave drawings and petroglyphs depicting these ant- people of Hopi legend, they bare some resemblance to what we today refer to as "Grey" aliens, some theorists also claim a resemblance to the hypothesized Reptilian Race.
Hopi Flying Shields
Another interesting tidbit from Hopi lore is their flying shields. During the Third age that ended with a great flood, similar to Noahs flood and that of the Gilgamesh epic, the Hopi legends state that people built flying shields with the capacity to move rapidly between distant points in the World. These flying shields are quite similar to Vimanna Aircraft of Ancient India - the flying saucers of the ancient Indians on the other side of the Globe - the Indians of India. The Hopi called their flying craft 'patuwvota'.
The other people hardly heard them, under the leadership of the Bow clan they began to use their creative power in another evil and destructive way. ... some of them made patuwvota and with their creative power made it fly through the air. On this many people flew to a big city, attacked it and returned so fast no one knew where they came from.... soon the people of many cities and countries were making patuwvota and flying on them to attack one another.

The flying shields of the Hopi vanished at the end of the third age, the Great Flood. As described by Hopi legend
"See" said Sokutnanag, "I have washed away even the footprints of your emergence, the stepping stones which I left for you. Down on the bottom of the seas lie all the proud cities and flying patuwvotas." The Book Of Truth A New Perspective on the Hopi Creation Story - Pg. 21
