Anonymous users2024-02-08Human beings are just a creature on earth, evolved from Australopithecus, and are no different from other animals except for their high IQ. It's just a philosophical question, and it seems difficult to explain in words, perhaps it is the result of natural selection, destined for someone to change the world......
Remember.

Anonymous users2024-02-07This is the result of the evolution of life, first pure matter without life, then active protein-like organic matter, and then evolved cellularized organisms. Then, after hundreds of millions of years of evolution, humans finally appeared. Archaeology and modern research on primates have proven a certain degree of truth that man evolved from monkeys.
Man is an intelligent creature, and this is the main difference from animals. Of course, Adam and Eve are just religious legends, and you can check the evolutionary history of the specific human origin, so I won't say much here.

Anonymous users2024-02-06Hello....I'm a member of the Life Choir After Today, I Whisper: My fantasies are just fantasies....Life originates from and is a product of the earth. Even as Crick (F
Crick believed that life came from outside the earth, and that the earth is still the cradle of life. Life today appears to have been regenerated, reproduced and evolved by the first organisms, resulting in countless life forms that spread across the earth. Archaea, and later bacteria, multiplied rapidly in water, in the air, and on the ground, constituting a biosphere for more than 2 billion years.
The members of this biosphere communicate with each other, which in turn gives rise to fungi and then eukaryotes. They then assemble and organize into multicellular plants and animals. Life spreads out in the oceans, they land on land, fill the world with trees and flowers, and fly into the sky with insects and birds.
As a result, the "Tree of Life" was formed and grown on Earth. Humans are the most bizarre branch of this evolutionary tree of life. Therefore, the life born on Earth and the Earth are inextricably linked.
Why does nature have human beings: because the existence of human beings is inevitable, and it is a miracle that there is no life in such a vast universe? It's just that it happened very accidentally on Earth, and besides, how lonely it would be if there was no life in such a large universe.
As for the eyes open in front, I think the answer can be found in Darwin, why the mouth is long. The way life survives is to take in energy, eating is just one of them, there may be many other ways (such as ** to get energy) but it is not common for us, As for the following questions, they are all about human beings"There are 4 limbs that can carry things and walk, why do you have a digestive system, an excretory system, why do you have a nose, eyes? Is it a coincidence that all of these are indispensable? Human beings are special products of nature, and these are all about human beings.
It's not surprising that humans are different from other animals, maybe something else"Humans"It's strange to see that we have noses and eyes...

1. The temperature is moderate, that is, the distance from the sun is moderate, neither cold nor hot.
2. There is an atmosphere that can protect life, especially the ozone layer that blocks ultraviolet rays.
3. It has a stable magnetic field that can resist the "solar wind" and other deadly high-energy cosmic rays.
4. The composition of the atmosphere is reasonable, there is oxygen for breathing, carbon dioxide for the production of oxygen, and a stable nitrogen for most of the atmosphere, which prevents organic matter from being too active and burning.
5. There is water, which is said to be brought by an asteroid.
6. There are amino acids, which are the initial and basic substances of life.
Because people's vigilance is becoming more and more serious now, this is also related to what is happening in society, some people are not not kind, but can only be unkind, even if it is difficult to endure in their hearts, but when they see others in difficulty, they still do not lend a helping hand, because they may not know that they have been falsely accused, just like a very serious problem in society some time ago, the old man fell down and could not help, and some people were falsely accused after helping the elderly, how can this not make people feel cold, who dares to do good deeds again, Because pretending to be indifferent is also a way to protect yourself.

All human beings are born with the instinct of faith, and when people are desperate, they will shout to me, oh my God, who can help me. Man needs water and food to live, and so does the human spirit, which needs rest and spiritual food for the soul. I suggest you look at the Bible.
The structure is different, the absorption and reflection of light at different frequencies are related to the dielectric constant, permeability, and conductivity, but the latter quantities are related to the structure, that is to say, the arrangement of the atoms.
