The 10 most interesting mysteries of lost civilizations (Part 2)

America was discovered by Christopher Columbus in 1492, but there is much evidence that explorers from many other civilizations came to America before Columbus.

The exciting unexplored mysteries of lost civilizations

6. American expeditions

Roman and Greek coins , ceramic artifacts of ancient Jews and Asians in the United States and Mexico were found, and the statue of Isis and Osiris of Egypt in Mexico.

There are also traces to prove the presence of the Egyptians at Grand Canyon . The expeditions to the Americas are also mentioned in the myths and folklore of many nations.

However, so far we have very little information about Christopher Columbus's pre-expeditions.

7. Ruins off Japan

Scientists discovered strange stone structures, which looked like the ruins of a pyramid off Okinawa Island, Japan

Under a depth of 30 meters off the island of Okinawa , scientists discovered strange stone structures , which looked like the pyramid's ruins could have been built by some 'lost civilization' . People noticed the presence of paved streets, intersections, large churches, steps leading to squares .

Masaaki Kimura, a marine geologist at the University of Ryukyus, said: 'I was stunned to see a giant gate lined up from many large rocks similar to the prehistoric buildings commonly found in cities of Incas'.

For more than 15 years, Masaaki Kimura has dived into this area to measure and understand its formation. Many people speculate that this may be the continent of Lemuria .

8. Continent of Lemuria

If Mu world really exists, where is it?

Lemuria, also known as Mu , a continent that exists in the Pacific Ocean around the same time as Atlantis , seems to have been forgotten, even though it is the spiritual antagonism of Atlantis. According to Aboriginal legend on many islands, tropical paradise Mu is somewhere in the Pacific Ocean but has been submerged with its citizens thousands of years ago.

The Lemurians believed that materialism was not important; instead, they paid more attention to healing, art, music and spirituality. Until now people still argue whether Mu world really exists, if so, where is it?

9. The city sinks off Cuba

The city sunk off Cuba?This is still a question without an answer

In May 2001, Canada's Advanced Digital Communications (ADC) Digital Media Company made an interesting discovery while exploring the seabed of Cuba's territorial waters. The underwater ultrasound locator captures pictures of rocks that have symmetrical structures, which look like the ruins of a city.

Paul Weinzweig, of ADC, said: 'Nature cannot create such masses of rock, certainly not the hand of nature but we still don't know what it is'.

Later polls attracted much attention from the world including National Geographic. In 2003, a research team sent a small submarine to explore the works of 'a large urban center'.'But we still don't have enough evidence to confirm this is a city , ' Paulina Zelitsky said.

10. Egyptian treasures at Grand Canyon

The map to the treasure is hidden in the Grand Canyon

On April 5, 1909, ArizonaGazette published an article titled: 'Exploring Grand Canyon: Breakthrough findings proving that ancient people emigrated from the East'. According to the article, the expedition sponsored by the Smithsonian Institute found many artifacts that confirmed the existence of treasures hidden in the Grand Canyon.

Inside a cave, stones were found with hieroglyphs, bronze tools and weapons, statues of Egyptian emperors and mummies. So far no one has confirmed the authenticity of the article because it is impossible to determine the location of the Grand Canyon. Many people believe that this is just a rumor rumor, some people believe that a certain force has erased the trail of the Egyptian treasure.
