Everything has been hidden from us.
Another race of giants that exist(ed) are the ones depicted at Easter Island. People didn't even know that the majority of the statue was underground until recently.
According to the late David-Wynn Miller these giants landed in a 300x50x2mile spacecraft in the center of Greenland a few thousand years ago where it still remains fully-operational. It supposedly acts as a weather machine and has a 200 mile-wide dampening field where no electrons can flow.
Lastly, have you heard about the giant of Afghanistan that U.S. Special Ops shot and killed?
Yes I have heard about the Afghanistan giant, I left out any reference to Genesis 6 giant reference and the Anunaki. There are so many solid historical references in North America alone. The establishment created a fictional history that is boring compared to the big picture😃
