Hello,
I'd like to point out the many discoveries that are hidden because of how they fall out of the narrative of mainstream archeology.
The first discovery was the Klerksdorp spheres found in 3 billion year old deposits in South Africa. These spheres are as mysterious as they are precise in their geometry.
The second discovery is the amazing monoliths found at Gobi Tepi in Turkey. These monoliths are dated to be over 11,000 years old and could be considered the oldest structure made by humans after the end of the last ice age. This structure also coincides with the location of where the first strain of wheat that stayed on the stock is from, making the transportation of food possible for early civilizations.
The last amazing unexplained discovery is the golden airplane figurines of Central America. These tiny figurines not only resemble airplanes but when people created models of them, they actually flew. Some say these are exaggerated representations of insects or fish, but either way they remain mysterious.
