There are several theories about modern technology that humans might have possessed thousands of years ago, and these versions sound pretty fantastic. Some of the scientists believe that nuclear weapons could have existed thousands of years ago and even nuclear wars could have occurred. In addition, there are versions that the aircraft were also quite real and there are various signs of this that are found in various parts of the planet, including the Egyptian pyramids.
The glider figurine was found in one of the pyramids in 1891 and became a real sensation in the scientific world. The age of the find is several millennia and according to some experts, the ancient Egyptians may have possessed the technology of building aircraft. The figurine from the pyramid of Djoser in Sakkara surprised scientists by the fact that next to it lay an ancient papyrus, on which the phrase "I want to fly" was written.
12 years ago, a scientist named Simon Saunderson decided to build a real glider from a figurine and it took off. However, in order to operate this aircraft, a rudder was needed, which was not on the figure. It is difficult to really prove that the Egyptians knew how to build airplanes and more research is needed on this topic, but too many drawings and texts indicate this possibility.
