Why are there people on earth 5, why are there people on earth

There is life on all major planets, but the state of existence is different. Different spatial levels have different forms of life. Just like we usually say that aliens can't actually be human, that's because we're used to speculating about things according to the way we think.

During a long space trip, a group of life forms came to the earth, because of the loss of energy, they could not go beyond the earth's magnetic field gravity, could not return to the original space, had to live on the earth, and became the ancestors of our "humans".

In fact, in a much longer period, all space life forms were the same ancestor, and because of the evolution of time and space, there were great differences in the degree of difference.

Because there are orangutans, and the environment guides them to transform into Homo sapiens, in a specific environment, this transformation teaches advantages, natural selection, and gradually this advantage is constantly improved, and the current man is formed.

Personally, I believe that the origin of human beings comes from the mutation of a certain living organism, just as people are afraid of the change of "avian flu" and irradiate "breeding rice varieties". When reproducing offspring, most of the offspring inherit the genes of the previous generation, but there are also individual inheritances that have genetic mutations. Just like pugs, when dogs were breeding offspring, freaks occurred, but people liked the pug's appearance and kept it.

The next step is Darwin's evolutionary theory of survival of the fittest.

Man evolved from primitive animals, and man has played a great role in transforming the earth's environment. Alien artificial. Rowing is a gift from the earth.

1 The Earth is in a relatively safe cosmic environment

2 The Sun does not change significantly over a longer period of time

3 The distance between the sun and the earth is moderate, so that the equalized temperature of the earth's surface is 15 4 There is an atmosphere on the earth's surface, which provides respiration

Evolved from primitive man!

Because God created it.

There is no why. The principle of anthropic.

In a Hegel phrase,"Existence is reasonable"

If there is no one, it will not be called the earth.

It's just a coincidence.

There were humans on the earth before, like the discovery of prehistoric airfields, and the discovery of necklaces in coal blocks 100 million years ago; Later, the surface of the earth changed, human beings disappeared, and the age of dinosaurs was born, and the age of dinosaurs passed, and human beings were born again, because earthlings and aliens live on the same kind of planet, which provides oxygen, carbohydrates, forests, rivers, oceans, vegetation, various animals, magnetic fields to generate electricity, various mineral deposits, wind, rain, and the alternation of the four seasons, which can make human beings reproduce, so there will be people on the earth.

Because life has developed to a certain extent, there will inevitably be intelligent life, maybe God favors the animal 'man' and gives him wisdom, and man will slowly stand on the earth!!

Because there are conditions on the earth that are suitable for human existence, human beings have been formed in a long period of time.

When the earth was first formed, it was an ocean, and in the primitive atmosphere, inorganic small molecules were excited by ultraviolet rays, lightning and other conditions to form some organic small molecule substances, which flowed into the primordial ocean with precipitation. In the ocean, there are several small molecules that accumulate and interact with each other for a long time, forming a relatively complex number of macromolecular substances, proteins, nucleic acids, etc., which gradually gather and form a primitive membrane separated from the surrounding sea water on the surface, forming a relatively independent system, and producing algae and lower invertebrates. Mesozoic:

The mass production and reproduction of plants and animals. The formation of the weather. The creation and extinction of dinosaurs.

Cenozoic: the formation and regularization of natural weather. The Creation of Humanity.

Because there are mothers on earth ... Mom gave birth, so there was someone.

Recommend Darwin's theory of evolution.

Just look at the first chapter of the Bible.

Why are you asking that?
