Live: Opening decryption Oxygen is highly toxic

at this point.

It is determined by modern science based on the ancient geology of the earth.

It's also about the Hades...

The greatest unsolved mystery.

Some people have analyzed that it may be at that time that a large number of meteorite belts rushed into the solar system.

Others say it's just a coincidence.

But none of them can explain why after that, the environment of the earth...

suddenly become so stable.

There has never been a large-scale meteorite impact phenomenon.

under the podium.

Ban Donglin and the others heard this.

He couldn't help but sucked in a breath of cold air again.

This unsolved mystery...

He'd known it before.

But now, following Qin Mu's live broadcast...

Easy to solve!

Earth as a petri dish, that phase was naturally designed to shape the primordial oceans and primordial atmosphere.

After shaping is complete, life is born.

Unless the alien civilization is stupid...

Will continue to hit the earth! .

Chapter 140 The Great Oxidation Event, the appearance of oxygen!

and so……

After the Hadean epoch, there have been no large-scale impact events.

of course.

Except for the meteorite impact events that the ancient Chinese civilization faced during the Jurassic period.

The alien civilization at that time...

It was for the purpose of destroying the world, so a large number of meteorites were mobilized from the direction of the Oort Nebula to smash down.

When everyone was shocked.

Qin Mu smiled slightly, and said the second major event of Minggu Era.

"Secondly, during the period of the Hadean Eon, another major event happened, that is... the birth of the moon!"

The voice fell.

Everyone below - couldn't help but widen their eyes.

The origin of the moon...

Qin Mu has said it before.

From the impact of a giant planet, so the moon was formed.

The original impact event also led to the formation of Buzhou Mountain connecting the moon and the earth!

There was also the Pangu project, which pushed the moon directly away from the earth!

but……

After Qin Mu's explanation this time.

They learned the true purpose of the appearance of the moon!

":小':说!'资"!源!分?,享?（;:6"9;8:9?!2'?5:,8'5!?0;）　　“潮汐之力！”

Experts and professors in various fields immediately came up with these four words in their minds.

Appearance of the moon...

In fact, it is also an important part of the birth of life!

Its tidal power stirred the sea water and accelerated the process of life from scratch.

"Actually, this period of the Hadean Era is the process of alien civilization building petri dishes."

Qin Mu then added a sentence.

So during this period of time, all the big events that happened were for the purpose of building a petri dish.

"Third, according to the investigation of paleogeology, modern science has discovered that during the Hadean period, the general temperature of the earth reached 800°C!"

This is also a very important feature of the Hadean Eon.

Anyone who has studied ancient earth history knows it.

During this period, the temperature of the earth was surprisingly high!

but……

After thinking about it, Ban Donglin and the others understood the reason for the high temperature during this period.

"As we all know, the higher the temperature, the more intense many chemical reactions are. For example, the temperature of submarine hot springs is even around 2000 °C all year round."

"In the early days, when the genes enough to carry life information had not been formed on the earth, in order to speed up this process, the alien civilization transformed the earth's environment, making the earth in a state of high temperature for 8 million years!"

"It's... a bit like the heated glass sphere in Miller's experiment."

In fact, if you count the events of the ancient universe in detail.

You can discover that everything in this period is a preparation for the birth of life.

only……

The above three points, just thinking about it, make people shudder.

Earth's ancient times.

There are too many traces of the behavior of alien civilizations.

"And the method of heating the earth is naturally through those primitive atmospheres. The content of methane and nitrogen in the air accounts for almost 90.00%!"

"And these gases have a very good thermal insulation environment, which makes the temperature of the entire earth continue to increase!"

Then go on.

Qin Mu briefly analyzed the reasons for this phenomenon.

This is also the operation method of alien civilization.

"The reason why I joined the earth for 8 million years is not only to promote the violent chemical reaction, but also to... the birth of land!"

The voice just fell.

on the screen behind him.

The picture of the ancient earth has undergone earth-shaking changes again!

A large amount of seawater was evaporated, turned into water vapor, and entered the air.

Become a member of the original atmosphere.

As the moisture in the air increases, the moisture in the ocean gradually decreases.

at last……

A whole piece of land was exposed!

This piece of land was so vast that it was the only land on the entire earth at that time!

"After the Hadean Eon, the sea level dropped on the earth, and the largest land was born, which was also a preparation for the landing of marine life later."

A complete land and water environment is the best state for civilization evolution.

Alien civilizations are also well aware of this truth.

Therefore, after life is born, it controls the environment in the "petri dish".

Make the land emerge!

"And looking at the history of the evolution of the earth, we can actually find that every step of the evolution of life on the earth is designed by people, step by step, and interlocking."

Qin Mu's voice quietly resounded in the conference hall.

It caused everyone to ponder again.

indeed.

Today's "science popularization" content is all interlocking.

The previous step prepares for the next step.

Never took any detours.

The emergence of the earth...

Go straight to the evolution of life!

And look at the solar system today, and the countless observable planets in the Milky Way...

They have also evolved over countless billions of years.

But it was going round and round, looping in place.

Some even have no primitive atmosphere and primitive oceans yet!

……

Jiangcheng.

City station, in the background monitoring room.

Old Zhao swallowed.

After listening to Qin Mu's explanation about the ancient universe...

The more he thought about it, the more frightening he became.

The evolution of life on earth is completely formed under human control!

And it is the alien civilization that controls all of this!

"Good guy! Now I want to see, who else in the live broadcast room opposes the existence of alien civilization?"

He raised his eyebrows, lowered his head and swept around the barrage.

It turned out that the mood of the barrage...

In fact, he is about the same.

They're all terrified types.

It is no coincidence that evidence after evidence points to the birth of life on the earth.

It's not a coincidence, it must be man-made!

Alien civilization has existed since billions of years ago!

Such a long-term experiment...

It can be seen that the conspiracy of this alien civilization is definitely not small!

And in the screen.

Qin Mu went on to explain the next stage of the earth's evolution: "After the ancient epoch, an ecological cycle has been established on the earth."

"From the hot springs on the seabed, there are a steady stream of new species emerging. They have complete life genes, which are exactly what the alien civilization experiment needs."

"For the convenience of observation, they built a base on the moon."

"Gene sampling can be carried out at any time through the aircraft, going back and forth between the moon and the earth."
