This kind of speculation was summarized by Vladimir Putin, and now Liang Wuchang's statement is more direct.

The reason is simple, since so many ancient creatures can leave fossils in the strata, and the distribution range and number of preservation are often very staggering, if there is really a "prehistoric civilization", where are the constituents of this civilization and the items they made, will they be completely disappeared inexplicably?

Of course, Long Yun couldn't find any reason to refute such a statement.

He roughly understood Professor Liang's line of thought, that is, "if there is a 'prehistoric civilization', there should be 'Opaz'", which is equivalent to saying that "Opaz exists" is a necessary condition for "prehistoric civilization survives"; Not only that, but the professor's argument is even stronger than this, he believes that if there was a certain era of civilization before human civilization on the earth, then today, human activities have spread all over the world, and "Opaz" should have been found a long time ago, and there should be a lot of them, but the fact is that nothing can be found, and only the expected negative conclusion can be obtained.

Liang Wuchang also proposed that some scholars believe that there may be "prehistoric civilizations" on the earth, which leads to the development of human science and technology in a stepwise form:

“…… Yes, following in the footsteps of the 'predecessors', this is also an explanation of the development route of human science and technology.

What do you think, young man? ”

"I- I don't quite agree, Professor Leung, if that's what they say,"

As he spoke, the snooping of consciousness had already let Long Yun know Professor Liang's thoughts. He can speak up without fear of conflicting opinions. "The scientific development of human civilization comes from the heritage of 'prehistoric civilization'. But didn't you just say that people have never found a reliable 'Opaz' until now, then it is very strange, there are no remnants of previous civilizations, even if the 'prehistoric civilization' has developed scientific and technological achievements, how can it be mastered by human beings? ”

"Well, it's the same thing!

Haha, that's what I've always thought too. Grace ......"

Quite recognized by the young man's questioning, Professor Liang smiled while smiling, but he really couldn't bear the addiction to smoking, he took out the "Jiaozi" cigarette case in his pocket and took out one, and gestured to hand it to Long Yun, but stopped suddenly:

"Oh, I remember, you don't smoke, I'm not welcome to this old smoking gun, go out and smoke one first!"

"Ahh I'm waiting for you here. ”

From 9 a.m. to now, I have been chatting with the young people here for a long time. Although Liang Wuchang, who was addicted to cigarettes, drank a lot of tea, he couldn't resist the temptation of cigarettes, and he came back after a few minutes, with a shallow smell of smoke on his body:

"Oh, young people, the habit of smoking is not very good, we old guys, we were busy with projects and stayed up late to refresh ourselves, you have a long future, it is best not to smoke, the national tax revenue has our old smoking guns to contribute, you don't smoke yourself, and usually persuade the people around you."

"Certainly, Professor Liang, you can also reduce a few sticks a little, and use your discretion as a pleasure."

"Yes, that makes sense!"

Feeling that the young man in front of him was quite good at talking, Liang Wuchang smiled and sat down, "It's just human willpower, hehe, I also want to quit, now, it's okay to smoke less, if you want to quit completely, you still can't do it for a while!"

Okay, let's not talk about these trivial things.

Regarding the topic just now, Long Yun, what you said is right, if the step form of the scientific and technological development of human civilization is caused by 'prehistoric civilization', then there must be some medium to transmit knowledge, or actual engineering technology, this kind of thing is undoubtedly 'Opaz', but we can't find even one of them now, such an argumentation process is indeed quite rigorous, and it can probably be used to refute those people's arguments.

However, I said, young man, do you have any other ideas, and there really is nothing wrong with the argument just now? ”

"Oh, you mean ......?"

Being a little confused by the question, Long Yun quickly thought about it and couldn't come up with a reason, he looked at Professor Liang in confusion.

"Didn't think about it? Well, it's normal not to think of it for a while.

Then let me tell you my opinion, or 'guess', you can refer to it.

The so-called 'prehistoric civilization', whether this thing has ever existed on the earth, we are still not sure, right?

So, if not, the rest of the reasoning is all empty talk, but if there is, let's not talk about why there is not a single 'opaz' left, just the assumption just now, the so-called transmission of civilization must be realized through 'opaz', which is itself very problematic.

Long Yun, you might as well think about it, if our human race suddenly perishes now, ho ho, it will suddenly encounter some catastrophe, then many years later, there will still be some relics of human civilization left on the earth; But what is the significance of these things to the groups of organisms that evolved into intelligence later, could it be said that a group of intelligent species evolved from cockroaches, excavating the remains of a certain nuclear power plant from the stratum, can be inspired at once, from the barbaric era of slash-and-burn farming to the door of atomic energy, can quickly discover the mystery of nuclear fission and fusion?

Haha, how is this possible, Grimm's fairy tales can't be more ridiculous than this!

So this kind of argument, my original idea has always been similar to yours, but now, I think it is meaningless at all, 'Opaz' such a thing, let alone not there, even if there is, it will not play any role in 'guiding the development of human civilization'. ”

"Like...... It seems like that, well, Professor Liang. ”

In the face of Liang Wuchang's mouth, sitting on the side and listening to the clouds, Long Yun felt very funny about the wild fantasy of "Xiaoqiang evolves to rule the world, excavate 'human relics' and enter the nuclear energy era", to be honest, he doesn't think that species like cockroaches will evolve intelligence, Darwin's evolution theory is not such a meaning.

However, this was beyond the scope of today's discussion, and he continued to listen to him without interrupting again.

"Actually, compared to 'Opaz', I, even though I am a researcher with a background in electrical automation, often think about this question.

After all, the development of science and technology in human society is a research direction of great strategic value in the current era: with so many sentient beings, crammed into a small earth, what kind of internal laws are there in the development of science and technology, can they be recognized, grasped and utilized, or can they only spend a huge amount of money every year, and then wait to see how much they will gain?

This question is of great importance to the decision-making body, and it is an intriguing mystery for those of us who are engaged in research.

It's not easy to answer, hehe, it's not easy at all. ”

Professor Liang's explanation, maybe mixed with some emotion, although Long Yun next to him consciously snooped as an aid, after all, he lacked the corresponding life experience, he sat on the sofa without saying a word, looking at Liang Wuchang who was staring down and muttering, his eyes fell on the professor's slightly gray hair, and the thoughts from the superpower were extremely clear, obviously, for Liang Wuchang, who studied the history of science and technology, this problem had plagued him for many years, and until now he couldn't find any clue. This is indeed quite a difficult ordeal for a scientist.

As the professor's emotion landed, for a while, the office became silent.

After a while, he woke up from the memories and confusion of his research work, Liang Wuchang's expression gradually calmed down, he used to have a straightforward and cheerful attitude, but today he was distracted in front of Long Yun, probably because he was usually immersed in endless research work, and dealing with people around him was often about work.

Speaking of which, the sturdy and focused young man in front of him, although he had only seen it a few times, Liang Wuchang had a very good temper, if it weren't for this, probably even if he had a lot of leisure at the end of the year, he wouldn't necessarily sit here and chat with Long Yun like that.

The emotion came to an end first, and Professor Liang, who came back to his senses, drank a few sips of tea, he had already discussed "prehistoric civilization" with Long Yun, but now he suddenly raised another topic:

"I said, young man, about 'prehistoric civilizations,' I'm pretty much the same.

'Yes, or no', of course, this is a question, but it doesn't make much sense to continue to discuss, I have another idea, and I'll discuss it with you here: Long Yun, have you ever thought about if, just if, 'prehistoric civilization' really exists, then, any kind of civilization must have its creator, and the creator of human civilization is of course people, so what about 'prehistoric civilization', who is the creator? ”

"Who? - Isn't it human? ”

Regarding Liang Wuchang's question, Long Yun was still thinking about the existence of "prehistoric civilization", although after talking to the professor, he was not optimistic about this issue at all, feeling that there would be no such existence in the real world or in the parallel world. Now, when he heard Professor Liang's abrupt question, he blurted it out without thinking about it, but it attracted a smile of implicit denial from Liang Wuchang and a nod and jaw that followed:

"Human, well, this answer is easy to think of.

In the environment of the earth, if there is any species that can gain wisdom in evolution, and even gradually appear civilization, hehe, the biological community is also divided a lot, my personal opinion, except for the primate of the ancient ape, other species are still very difficult.

Since only evolved Australopithecus, or man, could have established civilization, let's just think so.

So – don't you think it's strange?

Okay, let me make the question clear, if the 'prehistoric civilization' exists and was established by human beings, then this 'prehistoric civilization' no longer exists, but what will be the reason, what kind of disasters or other events can make a civilization completely extinct? (To be continued......)
