Gobekli Tepe - The World May Never Know.

[Maxmars]

I have to point out that it is not a "secret."  It is political and cultural leverage.

Unlike some, people have been 'marketing" their "ownership" of heritage that may not have been theirs... (unlike, say the many people's of South America who never tried to maintain that "we built this," they rather said "we don't know who built this, it's been here since we can remember.")

And it is not "humanity" it is being kept from, it's the rest of the world.

Past civilizations is a realm that only certain cloistered "academics" have been allowed to authoritatively opine on, and that restriction has consequences.
