Back in 1947,
A group of Native Americans witnessed a UFO crash and they arrived
on the site before the military arrived.
They rescued an injured extraterrestrial, and helped bring him back
to health.
In return of his gratitude to the Native Americans, the alien
imparted a special story of the Hidden History of Planet Earth to
these folks. The story is the "terra papers."
Terra
papers Linky:
Well I dont really believe the whole 'terra papers' story, it is
just an interesting story to be read thou, that's all.
Holy Crappppppp 
You'll be the Judge!
