Was there a civilization on Earth before human civilization?According to the current scientific evidence, there was no conclusive evidence that there had been other civilizations on Earth. However, some scientists and archaeologists believe that there was once a highly developed civilization on Earth, but these civilizations may have gone extinct.
According to the research of some archaeologists, there were some highly developed civilizations on Earth, such as the ancient Egyptian civilization, the ancient Indian civilization, the ancient Greek civilization, and the ancient Roman civilization. However, the origin of these civilizations in historical records can be traced back to about 3000 B.C. Before that, there may have been other highly developed civilizations on Earth, but whether these civilizations were recorded or discovered is still unclear.
Some scientists believe that there were some highly developed alien civilizations on Earth, but these civilizations may have gone extinct due to various reasons such as technological explosions, interstellar collisions, cosmic radiation, etc. The existence and extinction of these civilizations may be determined by the random and unpredictable nature of the universe.
In short, there was no conclusive evidence in the scientific community to prove that other civilizations once existed on Earth, but this did not mean that this issue was not controversial and worthy of discussion.
Is there a prehistoric civilization on Earth?The existence of prehistoric civilization on Earth was still a controversial topic.
Some scholars and researchers believed that there was a prehistoric civilization on Earth. They pointed out that Earth's history was long and complicated, and it may have experienced the development and destruction of many different civilizations or humanoid civilizations. They also proposed some clues or evidence that were considered prehistoric civilizations, such as the Mayan civilization, the Egyptian pyramids, the Hanging Gardens of Babylon, and other relics that exceeded the level of human technology at that time. There were also footprints on trilobites, nuclear reactors in Africa, and so on. The Baghdad battery and other discoveries far exceeded the time of human technology or human appearance. However, the existence of prehistoric civilization was not widely recognized by the scientific community.

Some scholars and researchers raised the possibility of prehistoric civilization. They believed that Earth's history was very long and complicated, and it might have experienced the development and extinction of many different civilizations or humanoid civilizations. They also pointed out some clues or evidence that were considered prehistoric civilizations, such as the Mayan civilization, the Egyptian pyramids, the Hanging Gardens of Babylon, and other ruins or relics that exceeded the level of human technology at that time. There were also footprints on trilobites, nuclear reactors in Africa, Baghdad batteries, and so on. However, there were also some archaeological discoveries that proved to have nothing to do with prehistoric civilization. For example, the murals in the ancient caves in southern Spain 65,000 years ago were verified to be left by Neanderthals and not products of prehistoric civilization.
There is no racism if there are no other countries ... at least at the beginning, there is only Huaxia and/or Chinese civilization ... you read right Chinese civilization, not Earth civilization...
