2. The tubes of Baigong
The tubes were found in 2002 at Mount
Baigong,in the province of Qinghai(China).
The scientific analyzes indicate that the
tubes were around 150 thousand years old
(period in which, it is supposed,the humans
hadn’t even reached China). It was created
by materials that at that time didn’t exist,
an ancient human society that would have
disappeared without a trace in history. The
theory is that the mount Baigong has a
structure that looks like pyramid that was
“devoured” by the environment. How? If at
that time they didn’t have this materials?
Nobody knows.
