They discovered an ancient monoplane in an Egyptian pyramid.

You participated in excavations in Sakara, a location not far from Cairo, in the year 1898, lots of pyramids and old tombs. When you feel like Indiana Jones, I hope you discover something very incredible to achieve fame: mummies, gold texts, and treasure maps. A wooden bird is waiting for a famous pharaoh. You seem to be terribly disappointed like a standard toy that is still in good condition. You have no idea how many years will pass. It would be suggested that your bird was, in reality, a vintage monoplane. Consequently, the object known as the Sakara “The bird” is constructed of sycamore wood. Birdie only has a seven-inch wingspan and is about 40 grams in weight. An authentic memento from Egypt may say it exceeds 2000 years old and plain, with no carvings of feathers or other complex embellishments. It does, however, have a beak and eyes, giving our wonderful bird the appearance of a hawk, the emblem of the deity Horus. Its tail is particularly peculiar in that it is squared and appears oddly erect, and it appears that the recessed area of it was the location of the now-missing piece.

Humans enjoy solving mysteries, so there have been several attempts to explain the use of the birdie. The first is that it was a ceremonial object. The second is that it was a toy for a child from a wealthy family. It could have been some sort of boomerang, which was popular in ancient Egypt.

Then, there was a theory that the bird had been used as a Weathervane, but this has been debunked because the figure has no holes or markings except for the one made at the Museum in Cairo to fix the exhibit on a stick so there was no way to hang it in the past almost a century after the bird was found. Egyptologist, Dr Khalil masiha, proposed a new theory that it could have been a model of a monoplane

Dr. Masiha further stated that it was common at the time to place miniature models of technological inventions in tombs, so did the ancient Egyptians really invent the plane in 200 BCE, which would upset their Wright brothers, who are considered the inventors of aviation, who made their first flight only in 1903.

There's only one way to know for sure, and that's to test the model, but the Egyptian Museum would never let one of their prized exhibits fly around like a toy, which is why glider designer Martin Gregory built a similar model, this time out of balsa wood, and concluded that even with the missing tail plane, the plane wasn't much of a flyer.

This didn't sound convincing enough to the History Channel, so they asked an aerodynamics expert to build another replica of the bird. He tested it in weather conditions similar to those in Egypt and was impressed with the little plane's abilities, so if they did invent the Prototype of a plane back in the time of the pharaohs, it would be a good example of an oopart that's an out of place artifact an object that's way ahead of its time in terms of technology

The antikythera device was recovered from an underwater shipwreck in the Greek island of Antisera in 1901, and it has been labelled the world's first analog computer dated 100 BCE. The bronze mechanism could tell the position of the sun, moon, planets, and stars, as well as the lunar phase, dates of upcoming solar eclipses, and even the speed at which the moon moves through the sky. No one knows who used it or how or where it was made, but it's obvious that it's extremely precise and far ahead of its time.

The first flushing toilets were invented in the middle of the twentieth century, however the ancient Minoans on the Mediterranean island of Crete and the Indus Valley Civilization both came up with this Brilliant Invention some 4000 years ago.

The plumbing and sanitation were so well done that no one could design anything better until 2 000 years later. One ancient Minoan lavatory was discovered at the palace of Canosos it looks like it had a wooden seat set over a tunnel that directed water from a rooftop reservoir to an underground sewer other varieties got water from jugs only the super rich people could afford all this Glory

Back in 1931, mechanized doors were a cool, seemingly new invention.

However, the technology behind them is much older. In the first century CE, mathematician and engineer Heron of Alexandria devised a hydraulic system to open and close Temple doors. To put it into action, you need to light a fire to produce heat. There was a brass pot under the fire half filled with water. The inventor connected the brass pot to containers that acted as weight when the fire was burning.

They went down and pulled the ropes; there was nothing like a shop door opening in front of you before you could even consider.

Heron's door took hours to open and there was no way to stop it, therefore they only opened the doors once a day before visitors visited the temple to add some mystery during ceremonies.

It appears that the first battery was invented roughly 2000 years ago in Baghdad. This was discovered by a German archaeologist in 1938, an oval-shaped clay jar was created. Scientists are still unsure what was the purpose of it, and who was it for? According to one theory, it was utilized for precious metal electroplating of metals when it was filled with a mild acid. The battery, like vinegar, produced around a single volt of electricity. According to another theory, it was a vehicle for divine scrolls.
