If a file of historical value reaches the Smithsonian Institute, it disappears to thin and never heard again.
That is how science operates in America.
There is a YouTube presentation in Why Flies or WF that states that there was a civilization that predated native Americans.
This civilization has left artefacts and they are strangely similar to Indian, Egyptian and Tibetans.
Sitting and Standing Buddha are among them.
View this YouTube presentation before Smithsonian Institute put pressure for it to be removed.
It looks like CIA operatives are hard at work at Smithsonian Institute.
Good luck on them.
