What do we know about the billion planets that exist in the universe? Are they also deserted like the planets in our solar system, with the exception of the Earth, or can they have intelligent civilizations that previously visited Earth?
Some ancient sources indicate that aliens have been visiting our planet for a long time and sharing their knowledge with people. Some of the supposedly such civilizations developed rapidly, gaining knowledge about the structure of the Universe, but this was thousands of years ago. It is interesting that thousands of years ago, some peoples possessed knowledge that in the modern world began to be discovered only in the middle or end of the last century. If our ancestors knew about the structure of the Universe better than us, then where does this knowledge come from?
So the next finds in the Mexican Veracruz tell us that earlier people came into contact with aliens, as evidenced by the images on the jade stones. A certain humanoid is holding some kind of artifact in his hands, and apparently the transfer of the object to people took place. What knowledge was there? We can only guess!
However, scientists have confirmed the authenticity of the stones, which is already progress. Usually they say that these are fakes and hoaxes. According to preliminary data, the images refer to the times of the Mayan civilization, and as you know, this civilization was very developed, and then disappeared without a trace. So maybe they left the planet when they got enough knowledge?
