Artifacts themselves are archaeological objects or historical objects which are made or modified by humans. Simple examples are terracotta, metal and bone, earthenware, paper and so on.
Here are 10 amazing artifacts ever in the world that should not have existed in their day.
10. Antikythera Mechanism

Discovered in 1900, precisely in the largest shipwrecks in the southern part of Greece, the island Antikythera. Antikythrea Mechanism can be regarded as one of the most ancient artifacts in the world.
Until now, historians to archeologists have been unable to discover who the creator of this thing is. All they know from this thing is its originator comes from Greece. The reason why this thing is called an amazing artifact is that its complexity and technology will not exist until the fourteenth century, and this object itself is thought to have been made in 150-100 BC. The complexity that this object can do is to calculate various astronomical events such as lunar eclipses.
9. 300 Million Year Bolt

In 1966, a group of researchers made an expedition to find the remains of ancient relics around the Kaluga area, western Russia. Dmitry Kurkov, one of the researchers found a stone-shaped object that later when cleaned there is a kind of bolt or screws embedded in the object.
This bolt has a length of 3 cm and a diameter of 3 millimeters. it is said that these objects are 300 to 320 million years old, various theories and experiments performed, surprisingly it is known that these screws are not a natural result, but is man-made alias is an artifact.
It can not be predicted who or what creatures can make the bolt-shaped object even implanted into rocks for up to 300-320 million years.
8. Ancient Hammer

This hammer is very strange and unreasonable. An ancient hammer found in the rock studied turned out to be 100 million years old. The age of wood used as algae from this hammer ranged from 100 to 200 million years ago, plus iron from this hammer composed of 96% pure iron.
No one can explain the origin of the ancient hammer because the human civilization had not existed at that time, or could the aliens have a hammer left on earth?
7. Sky Stone

The stone was discovered in 1990 by a geologist and archaeologist named Angelo Pitoni, in the Sierra Leone region of West Africa. From the results revealed the composition of this stone that is 77% oxygen, carbon, silicon, calcium and sodium.
Research was carried out by various laboratories from the Universities of Geneva, Rome, Utrecth, Tokyo and Freiberg, but none of which could explain the origin of this stone. This is because this stone was not derived from the type of stone that existed on planet earth.
The mystery of this stone is the stone is estimated to date 12,000 BC (BC). Surprisingly, this stone is definitely not formed naturally because this stone has a color that seems to be an artificial color that is blue like the sky. From here the stone is named Sky Stone or Stone of Heaven,
6. 100,000 Year Old Switch

A variety of historical relics can be examined past from various fossils or similar relics, but these artifacts can not be explained scientifically. A switch-shaped artifact with 3 iron ends embedded in a granite stone was discovered by an archaeologist named John J. Williams in 1998. This stone has the appearance of an electrical component or precisely a switch, In fact it already has a magnetic force but is quite weak. These 3 iron-shaped switches have non-created elements of wood, plastic, rubber or other materials that can be described.
Various experts say that this thing is engineering or hoax, but the unexplained thing is how this switch is embedded in a stone without using glue or other adhesive material. Have human civilizations in the last 100,000 years been so advanced as Atlantis might be?
5. Acambaro Figure

This discovery can be said to be the discovery of a historic object that signifies a civilization in which humans interact with dinosaurs. In 1944, when Waldmar Julsrud was traveling around the Acambaro area, he found an artifact of a figure. He then pays local farmers digging up the remains of the figure and pays them for figures they can find.
From there Waldmar discovers more than 32,000 figures that are thought to have existed since the days of the dinosaurs. If that is true then this artifact can be said to be a remarkable discovery and can alter human history, since it is said that no man lived in ancient times when the dinosaurs were.
4. Dropa Stone

Discovered in 1938, in the vicinity of the Baian-kara-ula mountains by expeditions, these disc-shaped objects are found inside the cave. Inside the cave is found in various graves and decorations that decorate the cave walls such as images of the sun, moon and stars, along with people who have a long head or maybe oval.
The archaeologists then dug the remains of the grave and found a human skeleton that has a height of up to 3 meters with large bones. In addition to human skeletons they also found 716 odd dishes sent to various world archaeologists. These strange dishes are then named Dropa Stone.
One of the professors named Tsum Um Nui, said that he broke the code or writing that lies in this dropa stone. Tsum Um Nui said that alien plane crashed into Bayan Har shan area 12,000 years ago, this alien can not fix their plane until its end try to adapt on earth. There are tribes from the area hunting aliens but there are also some who are married to these aliens. You can expect it by yourself, many people disagree on the results of the hypothesis from Tsum Um Nui.
