The classification of alien civilizations may vary according to the research and views of scientists, but it can usually be divided into three levels to show the difference in their development and technological level. The first level is the lower level of alien civilization, which may only have limited technology such as energy weapons or limited space exploration. These civilizations may be in the solar system or on nearby planets, but they may not have created complex life forms or highly developed technology. The second level was the medium-level alien civilization. They might already be able to use nuclear fusion energy, advanced computers, and communication technology. These civilizations may already be able to explore the entire galaxy, but they may still face some technical and environmental problems. The third level is a highly developed alien civilization. They may have created a highly intelligent life form, mastered the mysteries of the universe, and even controlled the entire galaxy. These civilizations may have developed sophisticated space travel and time travel technology, but they may still face some unknown challenges and problems. It should be noted that the above classification criteria was only a scientist's point of view and was not universal. At the same time, due to our current limited exploration of alien civilizations, we are unable to determine which standards are more accurate.
