Love had a complicated influence on humans. It was difficult to simply judge that there was no love. On the one hand, if there was no love, some negative situations might be avoided. For example, in a relationship that was not smooth, a person might be repeatedly entangled, tossing and turning, unable to sleep, and their luck might also be affected. Their complexion and spirit might become decadent, their emotions negative, suspicious, full of negative energy, and produce more emotional internal friction. Moreover, love may sometimes cause people to make hasty and illogical actions. A drop in the level of serum in a person in love may lead to confusion and invasive thoughts similar to obsessive-compulsive disorder. However, on the other hand, love also brought many positive effects to humans. Good love was filled with positive energy, bringing joy and growth. It made people feel positive and full of expectations for everything, reducing unnecessary suspicions about things. From a physiological perspective, love activates specific areas of the brain, causing the release of chemicals such as Dopamine, Pitocin, and Adrenaline to bring euphoria. Intimate behaviors such as kissing can also relieve stress and pain. Interacting with a lover may help relieve headaches. Moreover, at the societal level, the development of the concept of love, such as the concept of free love represented by Qiong Yao's drama, reflected the progress of society's concept of gender relations to a certain extent. Therefore, one could not simply think that it was fine without love.

At present, there was no conclusive evidence that Earth was the only human in the universe. From the perspective of the evolution of life planets, a planet in the habitable zone would take at least 3 - 4 billion years from the birth of the first life to the development of complex life, and then to the emergence of intelligent life. Any problem during this period could cause intelligent life to not appear. Therefore, we may not have discovered alien civilizations yet. They may not have evolved yet. Although there might be about two billion habitable planets in the Milky Way, through modeling analysis, the probability of primitive cell life evolving into intelligent life was only one in a million. At the same time, there were also opinions that alien life could not be defined by Earth's standards. In addition to carbon-based life, there might be silicon-based life in the universe. They might not need water, oxygen, or even sunlight, so the possibility of life or human-like intelligent creatures on other planets could not be ruled out.

"This statement is not entirely accurate. Although most of the international palaeoanthropological community believed that human beings evolved from ancient apes through long-term labor, and experienced the stages of southern apes, homo homo, homo erectus, and homo homo. This view was based on many biological facts. For example, Darwin's " The Origin of Man " used biological facts to prove the kinship between humans and apes. Huxley also pointed out the fact that apes shared a common ancestor. At the same time, Engels put forward the theory of labor creating man, which also emphasized the natural factors in the process of human evolution. However, there were other views. Some people believed that humans might have come from extraterrestrials. For example, the trace elements needed for the formation of life on Earth might have come from meteorites with so-called evolutionary chains that landed on Earth. These chains gradually evolved into humans under the suitable environment on Earth. Because the natural formation of acids such as acids was a small probability event, this statement was also believed by some people. There was also the theory of the Creator, which was similar to religious views. They believed that everything in the world, including humans, was designed to be born. Some physicists also believed in the existence of a " Creator " due to the accidental formation of life on Earth and physical phenomena. In summary, there were many perspectives on the origin of human beings. It was not easy to determine that human beings could only be created by nature. The novel " Battle of Yin and Yang " is equally exciting. Everyone is welcome to click and read it! "

Not necessarily. Action comics can feature various elements and characters beyond just humans, like aliens, robots, or mythical creatures.
