    The Birth and Development of Mankind: Humans were born 5 million years ago. That is to say, 60 million years after the extinction of the dinosaurs, human beings were born Human beings are differentiated from the animal kingdom, and taxonomically, homo sapiens belongs to the subphylum Vertebrates, Mammalia, Primates, Anthropoids, and Hominis.

    About 4.5 million years ago, humans and apes began to diverge, giving rise to Australopithecus ramanacus, which later evolved from Australopithecus australopithecus 2 million years ago, and then further developed into modern humans. Regarding the development process of human beings, it is generally divided into four stages: 1. The early ape-man stage.

    It lived between 3 million and 1.5 million years ago, and already possessed the basic characteristics of humans, such as being able to walk upright and make simple gravel tools. 2. Late ape-man stage. About 2 million to 300,000 years ago, the body resembled a man, the brain was larger, and it could make more advanced paleolithic tools, and began to use fire, such as the Beijing ape man in Zhoukoudian, Beijing, China.

    3. Early Homo sapiens (hominid) stage. Between 100,000 and 200,000 to 50,000 years ago, it gradually broke away from the characteristics of apes and was very close to modern humans, such as Neanderthals in Germany. 4. Late Homo sapiens (newcomer) stage.

    About 4-50,000 years ago, the evolution of human beings at this time showed a significant acceleration, and the morphology was very similar to that of modern humans, and culturally, there were already the art of carving and painting, and ornaments appeared. For example, in 1933, the cave man on the top of Zhoukoudian Keel Mountain was discovered. At this time, primitive religions had already arisen and had entered a matriarchal society.

    In the late Homo sapiens stage, modern humans began to differentiate and form, and spread throughout the world.

    Human beings originated from forest apes, and went through four stages: ape humans, primitive humans, Homo sapiens, and modern humans, and developed step by step from primates through a long evolutionary process. After the transition from ape to man ended, the institutional form of human beings was still developing.

    Humans evolved from Homo erectus with a larger brain capacity, and modern humans and Homo sapiens belong to the same species. The development and complexity of the brain may be conducive to social life in groups, which is very conducive to cooperative prey, food gathering, and information exchange, thus giving Homo sapiens an advantage in the competition for survival.

    How man came to be is divided into three categories: 1. Man is the origin of Darwin's theory of biological evolution, which believes that human beings are the product of biological evolution, and that modern humans and modern apes have a common ancestor 2. Creationism 3. Chemical origin theory 1. I said that there is a legend of Pangu opening the world and Nuwa creating people.

    There is God in the West, Adam and Eve, said Noye Ark. From a worldwide perspective, there are: ancient Chinese mythology, ancient Greek mythology, ancient Indian mythology, ancient Egyptian mythology, Nordic mythology, ancient Roman mythology, and six categories of Muzheng Oak are currently the most popular types of mythological systems, of course, there are many myths that have not formed a system.

    Such as Mayan mythology, Persian mythology, Celtic mythology, etc. Myths are stories created orally by the people collectively, and quickly express the worship of superpowers, struggles, and the pursuit of ideals and the understanding and imagination of cultural phenomena. For thousands of years, it has been an immortal source of creation for literati and folk artists, and has had a profound impact on later generations.

    Myths are not a scientific reflection of real life, but are the result of ancient times when human beings began to think and explore nature and combine it with their own imagination. 2. Man is the origin of Darwin's theory of biological evolution, which believes that human beings are the product of biological evolution, and modern humans and modern apes have a common ancestor. Based on the fossil material of Australopithecus and hominin that has been discovered, the earliest humans may have appeared 3 million or 4 million years ago.

    The process of origin theoretically divides the process of human origin into three stages: the stage of Australopithecus; also man and ape stage; The stage of a person who can make tools. The latter stage includes the two major periods of ape and homo sapiens; They are further divided into two stages, early and late.

    3. It is the theory of chemical origin. This theory is the hypothesis of the origin of life accepted by many scholars. This hypothesis holds that life on Earth evolved step by step from non-living matter through extremely complex chemical processes over an extremely long period of time after the Earth's temperature gradually dropped.

    The origin of life should be traced back to the origin of the elements and chemical molecules associated with life. Therefore, the origin process of life should start from the beginning of the formation of the universe, through the so-called "big **" produced carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur and other major elements that constitute life. Humans may have originated in Africa.

    In the 20s of the 20th century, Australopithecus fossils were discovered in Africa, and many people believe that humans are the real place of human origin. Moreover, Africa has a vast territory and complex terrain, including tropical jungles and grasslands, deserts and mountain valleys, which is an ideal Qingfang area for human origin. In addition, many important hominoid fossils of the Middle Pleistocene have been found in Africa in the past few decades.

    Darwin said that monkeys evolved. It's a slow-growing process of genetic mutations! So you can't see the monkey change into a human because the time is too short!

    Man evolved from apes.

    First of all, creationism is stuck in an infinite loop, so it's hard to say it's true! For example, the theory that God created man is generally recognized in the West, which holds that God created Adam and Eve, and Adam and Eve created human beings.

    So who created God? If you keep asking, you will obviously fall into an infinite loop! Then there is the fact that if man can be created by God, why didn't God teach Adam the ability to create man directly and let him create man, but instead use the method of reproduction?

    So creationism is clearly incorrect!

    Second, the theory of evolution, despite its many supporters, seems to have taken hold of the theory of human origins. However, science must be evidence-based and experimental. Evolutionary theory, on the other hand, focuses on the transition from apes to humans due to environmental changes. But since the environment has changed drastically, why are there no fossils of transitional species between apes and humans?

    Why can't ape-to-man evolution be done in the lab? Therefore, in the face of the world problem of how the first man on earth came from, we cannot believe in the theory of evolution because of the huge flaws of creationism! And the proponents of the theory of evolution should convince people with reason, rather than prove themselves right by labeling others as ignorant of science!
