Brazilian media reported: Exploring scientists discovered a 13,000-year-old, 10km long cave in South America. The appearance of this news has attracted the world’s attention, because everyone wants to know who created it, plus the 10km length is indeed enough to attract everyone’s attention.
In fact, some caves are 10m long, some are several thousand meters long,… these caves connected together can be up to 10km long.

After this news, these intricate tunnels became even more mysterious. Several archaeologists and scientists came together to this giant cave, they wanted to know who built them? Is it left over by aliens?
Scientists say that this is definitely not naturally formed, because its structure is very complex, and they also do not match the standards of limestone caves. If you look closely at the cliffs of this tunnel, you will see many traces of excavation. However, they have not undergone a careful grinding process, as if someone had used primitive tools such as shovels to carve them.
The vast world is full of mysteries, because in order for humanity to survive on earth, many things have been created, some are naturally formed, and some are created by humans.
In ancient times, people did not yet have the technology to build houses, so caves – natural homes became the home of humans and some animals. Currently, there are many ancient caves discovered in the world. In South America, Brazil, there are up to 1,500 mysterious caves and tunnels in the jungle. To date, scientific researchers have not yet found the cause of the formation of these caves.
The caves are located in granite and black rock that have been weathered for a long time, and there are also a number of other cave structures. The size of each cave is different, the diameter of the cave can be up to two meters and the widest can be up to 4 meters.

In the cave, there are very clear traces of excavation. Because the number of caves is too large, scientists can only choose to analyze at the same time. Through the appraisal process, archaeologists discovered that the caves This existed at least 13,000 years ago. The question is, how large was the prehistoric population at that time, to be able to create thousands of such caves?
According to scientists’ explanations, the discovery history of these caves may have begun in the 30s of the last century. At that time, an archaeologist discovered the existence of underground caves in the Amazon river basin. Because at that time research capacity was very limited, so scientists could not know what these giant caves were used for, archaeologists finally concluded that: Maybe 13,000 years In the past, people built such giant caves, most likely to shelter from the rain.
Based on the traces left in these caves, scientists seem to have found the answer, they seem to know who built them. They speculate that the creator of the above mysterious caves is indeed not us humans, but Megatherium – a genus of ground sloths the size of elephants that lived 2 million to 8,000 years ago. living in the South American region created.
Its traces and paw prints are also quite consistent with the above statement. During the ice age on earth more than 10,000 years ago, Megatherium was one of the giant creatures at that time.
Megatherium can stand upright on two legs and move, and also has sharp front claws. These thousands of caves were most likely left by them. However, what makes it difficult for scientists to understand is that Megatherium is a solitary animal. If they needed to live in caves, there would be absolutely no need to dig such a large cave?

Moreover, these caves do not seem to have any living creatures in them, because inside there are no traces of fur, food, feces, etc. These caves were all found in a dense forest in northwestern Brazil. Currently, researchers are still extremely confused, not knowing why their scope is so narrow.
Readers, what do you think about these caves? Are they really dug out by some giant creature, or by ancient humans, or by some other mysterious creature that humans don’t yet know about and left traces behind? This?
