Is it true that mermaids exist?

 There is a video available on YouTube showing the body of a mermaid stranded on the beach, titled "Echte Meerjungfrau nach Hurrican 2015 gefunden" (Real Mermaid Found After Hurricane 2015).

The upper part of the body appears human, while the lower part forms a large fin. It is suspected that such a body may have actually been found stranded, which could prove the existence of mermaids.

It turns out that this was just a hoax and an illusion, merely a property created by Joel Harlow for the film Pirates of the Caribbean: On Stranger Tides. To this day, there is no evidence of the existence of aquatic humanoids ever found.

In the past, Beluga whales were often mistaken for mermaids because they had "knees" similar to humans.

The photo that went viral was actually just a Beluga fish displaying its "knee," which should have been hidden under a thick layer of fat. What appeared to be a "knee" was actually an accumulation of extra fat surrounding a muscle that can be moved up and down; its function is to help the Beluga stay warm in its habitat in the very cold Arctic waters.

Under year-round cold sea conditions, any mammal other than whales or seals will eventually get too cold and die of hypothermia, whereas the Beluga whale manages to maintain the body temperature of warm mammals thanks to its fat reserves, which can reach about 40% of its body weight.

Just because the camera's viewing angle is correct, where the camera's position is such that it can capture the fat accumulation, it can actually be moved up and down.

In August 2009, after dozens of people reported seeing a mermaid leaping in the waters of the Mediterranean in Haifa Bay, a beach in northern Israel, the government of the Israeli coastal city of Kiryat Yam offered a reward of $1 million to anyone who could prove its existence, a prize that no one has yet managed to win.

Stories about mermaids appear in folklore cultures around the world, including Europe, Asia, and Africa. In the Javanese culture of Indonesia, Nyai Roro Kidul is the goddess of the sea and Queen of the Southern Sea, and has many forms; in her mermaid form she is called Nyai Blorong.

What is the oldest civilisation that no longer exists?

 Every time you count 60 seconds in a minute, you are using math invented by a civilization that vanished over 4,000 years ago. Long before the pyramids of Egypt were conceived, the Sumerians built what historians widely consider the world's first true civilization, laying down blueprints for urban living that still echo in cities today.

Emerging in the historical region of Mesopotamia around 4500 BCE, Sumer was not a single unified empire but a collection of fiercely independent city-states, such as Uruk, Ur, and Eridu. These cities sat between the Tigris and Euphrates rivers, a volatile environment that demanded intense cooperation to master. To survive the unpredictable floods and scorching summers, the Sumerians engineered massive irrigation canals, transforming arid mudflats into highly productive agricultural centers.

This agricultural surplus allowed populations to boom and led to an explosion of innovation. The Sumerians are credited with a staggering number of historical "firsts." They invented the wheel, initially for pottery and later for transport. To manage the complex administration of their temples and grain silos, they developed cuneiform around 3200 BCE, creating the first known system of writing by pressing wedge-shaped reeds into wet clay tablets. They also gave the modern world its concept of time; their base-60 mathematical system is the direct reason a circle has 360 degrees.

Despite their brilliance, the Sumerian civilization eventually faded. The very geography that made them rich also left them vulnerable to invasion, as they lacked natural defensive borders. Over centuries of warfare, they were gradually conquered and absorbed by neighboring peoples, most notably the Akkadians under Sargon the Great around 2334 BCE.

Sumer did not collapse in a single catastrophic event. Instead, it underwent a slow cultural assimilation. By 2000 BCE, Sumerian had ceased to be a spoken language, replaced entirely by Akkadian, though Babylonian scholars continued to study it as a sacred and literary language for centuries. Today, the Sumerians are long gone, but the foundational pillars of their society—writing, law, urban planning, and mathematics—remain deeply embedded in modern human culture.
