When did the higher intelligent life come to Earth? 50

According to Mother Nature**, the famous science fiction master Arthur Clarke has said that any super-advanced technology is indistinguishable from magic. Indeed, if a time traveler transports an ancient person through time and space to the present day, wireless devices, airplanes, and even electric lights will seem like magic to him. At present, a team of astronomers from Uppsala University in Sweden is searching for "magical phenomena" in the night sky to determine the existence of extraterrestrial advanced intelligent civilizations.

They will search for stars that have mysteriously disappeared in space without any explanation, and scientists believe that a vanishing star may well indicate the existence of a vast energy-harvesting technology far beyond the comprehension of humans on Earth.

Any cosmic celestial phenomenon that challenges all natural explanations will be potential evidence of extraterrestrial intelligent technology, and the sudden and mysterious disappearance of a normal star will imply that it has a close relationship with a mysterious extraterrestrial advanced civilization.

To date, the Uppsala University team has analysed more than 300,000 cosmic rays** through a variety of night sky surveys to see if there are any sources of light that have suddenly disappeared. Due to the limitations of observation by the human eye, the results of the survey are not very obvious, but some suspicious areas have been identified that warrant further investigation in the future.

When the earth really wanders, it will meet those advanced intelligent life forms in space.

Before asking this question, think about whether biological evolution necessarily requires high intelligence. At least from the perspective of existing living beings, only human beings have "higher intelligence", and biological evolution does not use this as a standard, in fact, there is no standard.

The earth's organisms are composed of nucleic acids and proteins, and the functional fragments of nucleic acids are genes, and genes are reproducible, so organisms have the instinct to reproduce, and they live in order to pass on genes, and genes will change in the process of reproduction, and evolution is not controlled by the organisms themselves, and is affected by the environment. The "higher intelligence" produced by human evolution is the result, the result of the countless evolutionary directions of the ancient apes (because there is no clear direction, so there are countless evolutionary directions), and the organisms themselves have no right to choose, but only to survive according to the changes in their genes.

Therefore, the probability of the emergence of "higher intelligence" organisms in biological evolution is very low, and the probability of another "higher intelligence" life before humans is even lower. And advanced intelligent beings like humans, once produced will be "prosperous" for a long time, and the power they have mastered can greatly change the earth's environment, build (transform) the environment, and make it the most suitable environment for their own survival, but human beings have found the oldest paleontological fossils 3.8 billion years ago, but have not found any evidence of "advanced intelligent life before humans" to transform the environment, and the answer is self-evident.

Intelligence is not necessary for the evolution of life, but the impact of biological survival on the environment is inevitable, the former makes the probability of the emergence of higher intelligent life very low, and the latter allows us to judge whether there are other higher intelligent life in the history of the earth. The vastness of the universe can be described as vast, and there are too many planets in the universe to count, and we cannot rule out that there are no advanced intelligent beings on other planets. Nowadays, human beings are the only advanced intelligent species on the earth, but human beings are also developing, and the technology created by human beings is also developing, and in the future, human beings are likely to be replaced by self-aware artificial intelligence created by themselves.

Is Earth Lonely? Are humans alone? Embark on a journey to find extraterrestrial creatures.

Before human civilization, there were no other advanced intelligent lifeforms. Because there is no clear evidence of the existence of higher organisms so far, we are undoubtedly fortunate compared to other organisms.

No, because humans are the first highly intelligent beings known to exist.

No. Because human beings were the first highly intelligent beings born on the earth, there were no higher intelligent beings on the earth before there were human beings.

The main purpose of human existence is to enable the normal operation of the earth, to make the earth better, and at the same time to let other creatures have a better ending, to promote the evolution of other creatures, so that creatures can live in harmony on this earth.

The meaning of existence is to explore the unknown world of the universe, as well as to protect the ecological balance of the universe, and there is a saying that existence is reasonable.

The existence of life is meaningless, meaning needs to be found by people themselves, and human beings themselves are not given any special mission, just for better reproduction.

Actually, as far as I know, there is more than just the earth.

Human beings, the intelligent life, at present, are indeed the only intelligent human beings left, except for aliens.

It is said that in the past, there were four apocalypse, and each time before the apocalypse, there were great and developed civilizations, and we human beings belong to the fifth generation of intelligent civilizations on the earth. The evolution and evolution of human beings began in millions of years, and the age of the earth is 4.6 billion years.

What the earth would have been like before humans is the answer that modern humans want to explore.

Before there were humans, there were no higher intelligent beings on earth.

Before there were humans, probably no one knew what the Earth was like before.

Personally, I don't think there have been any higher intelligent beings before humans.

There must be, but we don't know it, we're reincarnated creatures.

What we know about this at the moment is whether it is not, and we will not know it when we find it in the future.

There is currently no scientific evidence that there were advanced sapient beings before humans.

In the past, there would not be any higher creatures than humans, and there would not be those that needed scientific certification.
