9. Djoser Pyramid
The Egyptians built their first pyramid, known to us today as the Step Pyramid of Djoser, around 4,700 years ago in the ancient necropolis of Saqqara. Djoser was the first king of Egypt’s Third Dynasty. His vizier, Imhotep, diverted from traditional building methods and materials by designing a six-layered, 197-foot (60 meters) high stone pyramid far unlike the rectangular dry clay brick monuments that were customary at the time.
8. Ufo Sightings In Idaho
Idaho ranked as the number one state for UFO sightings in 2020, tallying up an impressive -- or, perhaps, troubling -- 164 reports of strange objects seen in the sky. Some of these sightings can be easily explained. For instance, people around the world have been baffled by SpaceX’s StarLink satellites, which seem like an otherworldly string of white lights passing through the sky.
7. World’s Oldest Bridge
In the early 20th century, archaeologists in Girsu, Iraq discovered a monumental brick structure that was huge, but they had no idea what it was so they called it the “enigmatic construction”. Girsu was once the center of a large city state in ancient Mesopotamia, the Cradle of Civilization. This is one of the earliest known cities in the world. Now known as Tello, it was built during the third millennium B.C. -- around 4,000 years ago, and it was rediscovered in 1929.
6. White Island Mining Disaster
Whakaari, also known as White Island, is New Zealand’s most active volcano. It’s located roughly 30 miles (48 km) off the east coast of the country’s North Island. In September 1914, part of the volcano’s crater wall collapsed, triggering a landslide that sent mud and rock gushing into the lake below. All eleven sulfur miners on the island at the time were buried alive in the disaster.
5. Bosnia Pyramids
Amateur archaeologist Sam Osmanagich made headlines in 2008 with his adamant claims that the world’s oldest and largest pyramids are actually in Bosnia, near the city of Visoko. He insisted that they were built 12,000 years ago by an advanced ancient society, and his stories about them became increasingly more abstract in the following years.
4. Encoded Sword
During the 19th century, someone discovered a unique double-edged 13th-century sword in the River Witham in northern England. It contains a cryptic 18-letter inscription that runs down its central groove.
There are various names for skyquakes depending on where you live in the world, including Barisal Guns (India), Uminari (Japan), Mistpoeffers (Netherlands and Belgium), Lagoni (Italy), and Retumbos (Philippines).
2. The Stargate Of Sri Lanka
Located on a 40-acre (16 hectares) plot of land in Sri Lanka, Ranmasu Uyana is a park containing the beautiful gardens enjoyed by past royals. The gardens themselves and the nearby Tessa Wewa reservoir were built in the third century B.C., during the time of King Tissa.
During the early 2000s, archaeologists excavated at a site in Pattanam, a village in southern India where strange beads surfaced every year during monsoon season. Over the following years, they discovered a plethora of artifacts, including Roman amphorae, a 2,000-year-old dugout canoe, building foundations, glass beads, gold ornaments; iron, lead, and copper tools, and a wharf-like structure.
