On our planet there are various circles and drawings of huge sizes, which were still in ancient times and the mystery of such drawings does not give rest to many scientists, archaeologists and ordinary people.
It is interesting that despite the large size of such drawings, many of them are visible only from the air and people did not even know about their existence before. The Jordanian circles were discovered in the 20s of the last century and they impressed the entire scientific world. The diameter of twelve circles from Jordan ranges from two hundred and twenty to four hundred and fifty-five meters and scientists do not know exactly when the drawings were created and by whom.
New circles were recently discovered in Syria and Jordan, of which there are also twelve. Why did the ancient people need to spend time and invest enormous efforts so that the circles could only be seen from a bird's eye view? Some of the circles are not drawings, but structures of huge stones. A number of ufologists believe that such drawings are the airfields of the ancients and could have been built for alien ships. But is it possible?
