Are humans created or evolved?
The first unsolved mystery is controversial. Where did humans come from? The answer to this question may have different views in different people's minds. Some people think that God created man, while others think that man was caged in the earth by aliens. The special pursuits and beliefs of many famous scientists in their later years also made some people question whether the end of science is theology, and even denied what was once regarded as science.
I believe that people born after at least 90 years have already learned some contents of evolution in textbooks when they went to school that year. I believe that everyone will not think that people are monkeys, right? It is undeniable that even today, evolution is still a hypothesis and cannot be used as a conclusion. However, with the emergence of more and more fossil evidence, the hypothesis that human ancestors were forest apes and humans began to migrate from Africa to all parts of the world has been more confirmed.
Objectively speaking, although human beings all over the world are Homo sapiens and the only remaining species in the whole genus, we also have a general understanding that Homo sapiens who have evolved more than Homo erectus have gone through two stages, and Neanderthals, an ancient European human who once existed on the earth, disappeared as early as 24,000 years ago. The most likely descendant of Neanderthals and ancient humans in China is Xu Changren about 10 million years ago. However, due to the lack of fossil evidence of many important transitional stages, we can't 100% determine that human ancestors were long-recognized forest apes.
Have UFOs ever appeared in China? Are there aliens in this world?
Many people think that it seems that UFOs are more likely to appear in the United States, because many related reports you see now are related to the United States, and the Pentagon has attracted the attention of the whole world. However, when we look up UFO files in China, we will find that, in fact, the records about UFOs can even be traced back to thousands of years ago.
Because the ancients did not have the conditions to photograph the shape of UFOs, we can see that their descriptions of UFOs were exaggerated in words, such as describing the shape of what they saw as? Red dragon? And then what? Urn? Wait a minute. The appearance description of the spiral plane first appeared in the Ming Dynasty in China, but it can be found in? Chaozhou government records? Relevant records can be found in the literature. The earliest work to show pictures of UFOs was the work of a painter in the Qing Dynasty, and its name was Red Flames Flying.
Ten years later, on the evening of July 7, 20 10, a UFO appeared at Hangzhou Xiaoshan International Airport, which became one of the most famous UFO sightings in contemporary times. It is said that the person who accidentally saw the mysterious object was the crew, not the passengers or the radar. A point-like thing completely disappeared into the air after it glowed. This incident also caused many flight delays in that year, and residents around said that they also saw UFOs. At present, there are different opinions about this incident, which also makes it an unsolved UFO sighting.
There are many UFO witnesses all over the world, but after later confirmation, at least 95% of UFOs were dispersed in subsequent investigations. Except for those historical UFO incidents that can't be verified for a long time, the remaining 5% still don't know what they are. Objectively speaking, no one can say for sure that there are no aliens in this world, just as there were no humans on the earth hundreds of millions of years ago. Who can guarantee that there will be no aliens on other planets? Another kind of human? Alive
Why can't the earth allow human beings to reproduce? Where is the second earth in the universe?
Just as the earth has been born for billions of years now, mankind did not create modern civilization on the earth at first. Judging from the current understanding of the history of the earth, there were many creatures that no longer existed on the earth in the past, and one of the most familiar species was dinosaurs, because archaeologists unearthed a large number of dinosaur fossils and classified and named these extinct species, which ruled the earth for more than 100 million years.
Judging from the evolution of planets and species, both the earth and the sun have the day when life ends, and human beings live on the earth in the solar system. Therefore, if humans can't find a second planet suitable for their own survival, then the earth will be the first and last place to live. In fact, looking at the whole solar system, no planet has been proved to be suitable for human reproduction, and the planetary world outside the solar system is too far away from us. Therefore, our only choice at present is to wait for scientists to bring good news, and the rest is to maintain the current ecological environment of the earth.
Where is the second earth in the universe? Nobody can answer this question for the time being. It can only be said that there is a greater probability that it should exist outside the solar system. With the change of the earth's climate, unknown viruses suddenly appear more and more frequently in our lives, and natural disasters such as extreme high temperature, drought and flood also appear more and more frequently. All these are warning us that it is urgent to protect the earth and find a second earth.
