Images taken by satellites from space have long been incomprehensible to scientists. Strange objects are visible in the images, their formation and placement are devoid of logic. They look like small green islands in the middle of a lifeless desert. Over the past thirty years, scientists believed that these green islands are somehow created by nature. One version is associated with a tornado or hurricane that could bring plant seeds onto this lifeless soil.

This hypothesis existed but was in doubt. Nature is incapable of this. And only people could create such oases. Finally, the last assumption received strong scientific evidence. Green areas are areas that belonged to the inhabitants of Ancient Amazon. This is something like suburban areas where ancient people grew different crops.

They ate the resulting crops. In the southwestern territory of the Amazon, there are 6643 such green areas. Of these, 4, 7 thousand sites were recognized as artificial, that is, man-made. These are small elevations, their height does not exceed three meters. The total area of each plot is about 0.5 hectares.

Archaeologists have been able to explore 60 such zones. On each, they found ash, parts of seashells, animal bones. This suggests that people lived here. The islands themselves could not be created by nature, this is man-made work. The inhabitants of Ancient Amazonia built embankments using sand and stone, and the age of these buildings is at least 10 thousand years.

Hilly formations were not made accidentally - people were present at the sites from about December to March when part of the savannah was underwater after winter. And the next six months, this part of the savannah was chased by a severe drought. The created hills protected crops, including floods. Holes were made in them, which served as water stores, its ancient people used to water plants.

A chemical analysis of the soil in these places showed that the ancient inhabitants of Amazonia actively cultivated pumpkin, corn. The first crops could be made 10.3 thousand years ago, and corn was first grown here 6.8 thousand years ago. The land was well cultivated and fertilized. It is so good that its fertile layer to this day has retained its high qualities for excellent crops.
