Confirmed, Chilean Hamlet 14,000 Years Old

The long-held dogma that the Americas were not populated
until 12,000 years ago  has been dealt a death blow by the
latest findings at Monte Verde in Southern Chile.
The site has been settled for 14,000 years and it is a
collection of about 6 or so huts, making it the oldest village
in the Americas. Monte Verde was first excavated in 1976
but  the US archeology establishment refused to believe that
the site was as old as it seems. The latest evidence consists
of packets of seaweed that the people ate which
were C14 dated. See article;

Megaliths, 9500 BCE

Megalithic stone circles of 30 metre diameter with stones 5 meters high have been excavated in Turkey. But they date to 9500 BCE, some 4500 years before the earliest recorded megalithic structures. Furthermore, unlike the more recent megaliths which were built by horticultural/agricultural societies these were built by village-dwelling hunter-gathers. They are also covered in carvings of birds, pigs, lions and snakes.
