Before the appearance of human beings, could there be advanced creatures like human beings on the earth ...?

Yes! However, human beings are the most advantageous creatures in the history of the earth. In the last century, British scientists entered a mysterious and sacred cave in South Africa at night. Several bodies were found in it, and DNA tests showed that these bodies were five or six million years ago. At that time, human beings had not evolved. There are twelve constellations on the cave wall, and an undiscovered asteroid was found near Sirius. There is also a sentence next to it, which has been translated after many twists and turns: this is an asteroid invisible to the naked eye. Maya civilization is an outstanding representative of ancient Indian civilization in South America and ancient Indian civilization in America, named after Indian Maya. Mainly distributed in southern Mexico, Guatemala, Brazil, Belize and western Honduras and El Salvador. It was formed around 2500 BC, and an early slave country was established around 400 BC. It flourished in the 3rd to 9th centuries, declined in the 65438+5th century, was finally destroyed by Spanish colonists, and then disappeared in the tropical jungle for a long time. Similarly, in Greek mythology, in ancient times, there was a nation who lived in a permanently warm and sunny place in the far north, which was called "the promised land of the north". With the discovery of ancient animals and human activities in the Arctic, some people began to believe in the real existence of the "promised land of the North", and explorers and researchers began to look for this unexplored mysterious land. In Plato's time, people were already speculating that there might be life on the earth. Plato thinks that the earth is full of tunnels and caves. For a long time, the idea that there is a hole on the planet has been widely circulated in science fiction, and some people are even conducting different experiments to prove that there is indeed a hole on the earth. Is there any scientific reason for this idea? 70 years ago, the map of the Arctic showed that one third of this area was unexplored, which meant that there might be human life in the mysterious Arctic. However, Mark Satikov, Ph.D. in Geology and Mineralogy of the Russian Academy of Natural Sciences, is convinced that there are no caves in the Arctic that can serve as the entrance to underground areas. Maria Gaffry Rowe, a geographer at the Arctic and Antarctic Institute, also said that when she visited the Arctic, she didn't find any caves. Indeed, the Arctic is a sea covered with ice and snow. Many people who try hard to find caves are in vain. Nowadays, the new technology pioneered in 2 1 century can be used to study this field carefully. Experts in hollow earth theory have studied the earth's magnetic field and found that there may be several magnetic fields on the earth at the same time. Researchers speculate that there is another sphere with its own magnetic field inside the earth. They also said that the northern lights are gas, which leaked from the thin crust of the polar regions. Moreover, followers also stressed that when reaching the polar region, the compass will definitely swing in disorder. Many researchers also say that warm winds often blow from the North Pole, which proves that there must be huge caves there. However, most guesses about the empty earth are based on speculation rather than scientific data. That's why rigorous researchers don't comment on these theories. However, some researchers do believe that there are limestone caves under the surface. They think that if there were no caves on earth, it would be heavier. For some people, mystery on the ground is not enough. They want to keep looking for a new underground world. No one knows what happened underground, and there are still many unsolved mysteries to be solved. /d/2006- 10-24/083 1 1 19939 1 . shtml
