artificial caverns located at Phoenix Hill China.
This is one of the most
mysterious place on Earth. It is believed
that these caves are at least 2,000
years old. These caves are one of the
greatest structures ever excavated by
men. Researchers and archeologists have
been baffled by the size and precision
of the cave. Archaeologists, engineers,
architects and geologists from around
the world have tried to figure out the
answer of why, and how these caves were
built, but logical explanation is offered
by any one of them. Number 09 :  The underground city of Derinkuyu
This underground city is an
ancient multilevel underground city in
Turkey. The highest depth of this city is
approximately 200 feet. It is large
enough to have sheltered as many as
20,000 people together with their
livestock and food stores. Ever since its
discovery the city has challenged the
views and theories of archaeologists and
engineers. No one has any logical
explanation why and how it was built.
While some says it was created to
protect its inhabitants from climate
change extreme temperatures, or even war.
There are others who believe that its
purpose is far more mysterious.
Number 08 : Giant Stone Spheres. These giant Round
Rock could be the oldest stone sphere
made by human hands. They were first
discovered in South America in the 1930s
by workers who were clearing jungle to
make way for a plantation of Bananas.
This fears range in size from a few
centimeters 2 over 2 meters in diameter
and weigh up to 15 tons. This sphere proves
the existence of an advanced lost
civilization dating back more than 1500
years ago. No one have any idea that why
these giant stone spheres are made for.
Number 07: 2 Billion-Year-Old Nuclear Reactor
The nuclear reactors were discovered in 1972
in Africa, it sounds like a myth that an
ancient nuclear reactor that was churning
away 2 billion years ago. Scientists have
scratched their heads trying to
understand how it is possible that these
nuclear reactors developed in Gabon two
billion years ago. It's no joke, parts of
an African uranium deposit spontaneously
underwent nuclear fission for two billion
years. According to scientists, this
mysterious natural nuclear reactor had
the ability to produce modest energy.
Number 06: The Bosnian Pyramids
According to researchers around the world and the Head
of Anthropology at the American
University in Bosnia-Herzegovina
Dr. Semir Osmanagić, Ph.D.  the Bosnian
pyramids located near the town of

man-made Pyramids that have been
discovered on our Planet. The Pyramid of
the Sun with its 220 meters height
exceeds the Great Pyramid of Egypt which
measures 147 meters height.
Number 05 : The Baghdad Battery. The Baghdad battery or parthian
battery is a 2,000 years old set of
three artifacts which were found
together : a ceramic pot, a tube of one
metal, and a rod of another. While some
researchers refer to the object as a
battery. The origin and purpose of the
object remains unclear.

something what they say is the largest
batch of fossilized dinosaur eggs in a
mountainous area of chechnya. There is 40
or so eggs and his belief to date back
some 60 million years. Some researchers
believe they were laid by plant-eating
dinosaurs. The team of geographers
stumbled upon the eggs as they were
studying to uncharted waterfalls. About
90% Chechen scientists are certain of
their find. Number 03 :  The Antikythera Mechanism

eclipses for cylindrical and
astrological purposes, as well as the
Olympiad, the cycles  of the ancient
Olympic Games. Some of us takes these
artifacts as inspiration. Some of us
remain unaware of the mysteries which
are past hold. This is scientific
evidence of millions of years of
evolution and prosperity. The view of
some of us on these discoveries as
accomplishments of humanity working
together in long past circumstances.
Where others believe that advanced
life-forms or extraterrestrial beings
helped us for these accomplishments.
Number 02 : Nazca lines. The Nazca lines are a series
of large ancient geoglyphs in the Nazca
desert in southern Peru. The largest
figures are up to 1200 feet long. These
lines and figures can be seen only with

to astronomy and cosmology. The lines
were intended to act as a kind of
observatory, to point to the places on
the distant horizon where the Sun and
other celestial bodies rose or set in
the solstices. Other theories were
that the geometric lines could indicate
the flow of water, irrigation scheme or
be a part of rituals to summon water. It
has also been theorized that the lines
could act as an astronomical calendar.

as Rapa Nui to its earliest
inhabitants. Easter island's most dramatic
claim to fame as an array of almost 900
giant stone figures that date back many
centuries. The statues reveal their
creators to be master craftsmen and
engineers and our distinctive among
other stone sculptures found in
Polynesian culture. There has been much
speculation about the exact purpose of
the statute, the role they played in the
ancient civilization of Easter Island and
the way they may have been constructed
and transported. Leave your comment and
