Organic matter is a scarce resource in the universe, and only on the surface of the planet, a thin layer of life can be produced in large quantities. The use of industry to synthesize organic matter, especially complex organic matter, is definitely a thankless task. Humans can synthesize urea and methane industrially, but they want to synthesize amino acids from inorganic substances...... Of course, you can, but most of the synthesized amino acids are toxic!

In all amino acids, except glycine, there are chiral carbon atoms. Only the most sophisticated factories of biology can synthesize amino acids in a single chiral configuration.

Whether in animals or plants, ingestion of synthetic dex-amino acids is likely to have a huge adverse reaction.

Compared to complex organic matter, the separation of nuclear fuels such as helium-3 is much simpler, and any civilization capable of mining Jupiter-like can isolate an almost infinite amount of helium-3.

Precious metals such as gold and platinum are even less valuable. Taking the solar system as an example, the mineral resources on the asteroid 241 Germania are worth as much as 95.8 trillion US dollars, which is higher than the global GDP of 73.982 trillion in 2013.

This is just an asteroid, and if the core of a terrestrial planet can be mined, the metal resources are endless.

Therefore, in the interstellar trading market, organic matter is more valuable than conventional metal matter.

This is the interstellar common sense that humans have acquired from the mouths of the Bardits.

Of course, humans don't need to mine too much organic matter on Riley, just to refine some highly polluting scarce chemicals.

If these things are produced in the Kunlun Mountains, the pollution is too great and the production is limited, but there is no problem with putting the factory on the planet.

A planet, a little pollution, can be easily purified, which is also the opinion of scientists that has been demonstrated, this pollution will not greatly damage the living environment of native organisms.

On the other hand, even if people wanted to dig hundreds of millions of tons of coal mines, it was unlikely, and there simply wasn't so much place to load them in Kunlun Mountain. It is enough to get some chemical products.

After Sun Yuting said this, she bowed lightly: "...... To sum up, these evidences indirectly prove that the birth of the World Tree was 150,000 years ago, and there is no earlier record. ”

“…… The religious records of the Riley people also provide a small piece of evidence for the alien creation doctrine. 150,000 years is a very critical time node. ”

Zhang Yuan touched his chin and looked down in thought.

According to the records of indigenous civilizations, the so-called "World Tree" seems to have really appeared out of nowhere, without any excessive links in between.

However, this so-called evidence is still only circumstantial evidence, and it still cannot prove that the "World Tree" is genetically modified by aliens.

"This statement can still only be regarded as a conjecture."

One such conjecture is not enough to sensational the entire Kunlun Mountain, what is sensational is a series of subsequent conjectures!

First, the time node of the appearance of the "World Tree" on Riley Star is too close to the first interstellar civilization encountered by the Gliese civilization, the "Enlightener Civilization"!

The Gliese civilization, the first alien civilization that humans encountered, those drug-addicted pangolins.

There is a clear written record of the encounter between the Gliese civilization and the "enlightener civilization", which is a bit vague due to the large loss of historical data, but it should be around 10-150,000 years ago.

So, if the "alien creation theory" is true, is the so-called "interstellar civilization" the same?

Second, it was around this point in time that the human australopithecus on the earth came out of Africa and gave birth to the so-called Most culture!

The Moster culture is a Paleolithic culture in Europe, West Asia, Central Asia and Northeast Africa, named after the Le Mousti rock shed near Lesési, first discovered in the Dordogne department of France.

The culture began about 150,000 years ago.

Third, the Badit civilization, at this point in time, mutated into a long-term species, and its lifespan has increased by leaps and bounds from hundreds of years to thousands of years.

Yes, also 150,000 years ago!

This series of coincidences adds up, and it's not a coincidence!

150,000 years ago, in this starry sky, what was likely to happen, really possible......

Analyzing it like this, everyone fell into a real shock, as if they had seen a story that had happened...... 150,000 years ago, an extremely powerful civilization, wandering the galaxy, Orion cantilever, codename - "The Inspirer"!

For some reason, they swept across this star field, witnessed all kinds of indigenous civilizations, and left their own unique imprints, large or small, which may be insignificant, and may affect these low-level civilizations for a lifetime.

Even the earth...... Mankind!

When this was possible, everyone in the room held their breath, as if the oxygen in the air had suddenly disappeared.

It's incredible!

When it comes to more advanced alien civilizations, or even humans themselves, this matter becomes even more interesting.

A few minutes later, a crisp sound of music sounded, interrupting everyone's train of thought, this time the scientific research report meeting officially ended, the audience burst into lively applause, Dr. Sun Yuting bowed a little shyly, and then walked off the podium...... The rest of the time doesn't belong to her, who is a Ph.D. student.

However, not many people left the conference room, including Zhang Yuan himself, who was also excitedly discussing whether this civilization, known as the "Enlightener", had a profound impact on humanity itself.

Or is it a little help to human beings and promote the development of human beings?

This effect can be small, but it can also be significant.

After discussing this for a while, a historian stood up and said: "First of all, it is certain that human civilization is stuck in the Paleolithic Age, very, very long, at least three million years! These three million years of progress have been very small, and humanity has gone through an ice age, and it is even close to extinction......"

"In the past three million years, language may have been produced, but there should be no writing, and it can be called stagnant development."

Everyone nodded, this stagnation cannot be said to be a complete stagnation, but all progress depends on chance to occur.

The expert came to a conclusion: "So, intelligent creatures do not necessarily give birth to civilizations. For a civilization, having words and mathematics may be a relatively big hurdle, and it takes a lot of chance and long-term practice to have these disciplines. ”
