"Research? What do you mean?"

Petra seemed puzzled by Yang Yi's problem. Yang Yi said calmly: "Of course it refers to the aspect you are interested in. I am not very interested in the financial industry, and you are not very interested in this aspect, so why not discuss the things we like."

Yang Yi and Petra met with purpose, but the excuse he had for the first time to meet Petra was their common interests.

Sure enough, Petra was interested.

"If you talk about amateur research, no, it should be a hobby. In fact, there is no research anymore. Do you know? Since you showed those interesting Soviet archives last time, I have become more interested in what's behind the moon."

Petra sat up and said with interest: "Do you think there is any connection between humans on Earth and aliens?"

"Well, my focus is not on this aspect, so why not listen to you tell me."

Petra nodded repeatedly, and then she said with interest: "I have been thinking about a question, that is, are human beings lonely? Or are intelligent species lonely? Think rationally that we should not be lonely, because the universe is too big. Even if the birth of human beings, no, even if the birth of the entire earth is a coincidence, it is still too arrogant to conclude that there is no other intelligent life in the universe. What do you think?"

“Yes, feel the same.”

"There is a question. If there are other intelligent lives, or even intelligent civilizations in the universe, will they come to the earth? A symbol of intelligent life is curiosity about the universe. If you have curiosity, you will definitely explore. In ancient times, human beings began to develop endless curiosity and desire to explore the stars. So can we think that as long as civilization is formed, you will definitely explore the universe, because the exploration of unknowns is definitely a common civilization nature."

“Yes, agree.”

"Human civilization has been born for only more than five thousand years. I mean the existence of civilization rather than the human species. This is a very clear point. Then, in the more than five thousand years that humans have had primary civilizations so far, we have too many records of suspected but unproven contact with alien civilizations. But as I said, we only have suspected cases, but cannot prove any of them, right?"

Yang Yi thought for a while and said, "You are the Fermi paradox."

Petra nodded repeatedly, she seemed very excited.

Why are the conversations between smart people or the conversations between likes particularly pleasant? It is because they have a common language, and what one person says, the other person will understand and understand.

The Fermi Paradox was proposed by the Nobel Prize winner and physicist Fermi.

The simplest way to explain the Fermi Paradox is only two sentences. First, scientific inferences can prove that aliens exist, and the universe is almost infinite for tugboats. The evolution of aliens can be far earlier than humans, so aliens should have come to Earth, or even exist somewhere on Earth.

2. Aliens do not exist because humans have found no evidence of the existence of aliens.

Petra’s doubts can be summarized in two sentences of the Fermi Paradox.

"So what if we can prove that humans on Earth had come into contact with alien civilizations a long time ago?"

Petra asked Yang Yi this sentence with excitement, and then she became very serious: "Now, there are too many UFO sightings records all over the world, and there are countless, and there are many that can be explained later, but there are also many that cannot be explained."

Yang Yi found it interesting, he nodded and said, "Yes, you continue."

Petra raised his hands and said, "Is there a possibility that the main governments have joined forces to block the news? What if the main governments of various countries are consciously preventing the public from obtaining this news?"

"Well……"

"You are familiar with spies, so do you agree with this statement?"

Yang Yi smiled bitterly and said, "Yes, this is the truth."

Petra became very serious and said: "I am a conspiracy theorist. My attention to the third type of contact has started since I was a very young age. I will also be thinking about one thing, why did human civilization suddenly appear and suddenly become so developed? Evolution theory can explain the slow evolution of species, but can you believe this when human civilization exploded in the primitive era?"

Yang Yi spread his hands. He wanted to hear what research Petra was doing, but in fact he didn't want to discuss any research on alien civilizations with Petra.

Petra exhaled and said, "I was thinking, if the current official palace would block the news, what about ancient times? For example, the pyramids in Egypt, with the productivity and technology at that time, the existence of the pyramid itself was incredible."

"Uh, yes."

Petra laughed, and then she said proudly: "So I sponsored a website that specializes in searching for clues about the connection between alien civilizations and the earth. Most of the members of this website are doing this in their spare time, but we have a great time working together."

Yang Yi's heart began to pound, then he coughed lightly and said, "What did you find?"

"Uh, I really want to put the top secret file you gave me online, but you don't agree..."

Petra seemed helpless.

Yang Yi said indifferently: "Before you read the Soviet archives, have you achieved any results? Of course, any results are OK now. You know I am very interested in these, so I want to hear them."

Petra thought for a while and said, "Well, there are still some, but they can't be called something gained. It's just some clues. Oh no, what's frustrating is that there is no breakthrough progress at all. Everything is repeated in the old tune, such as the construction of pyramids, such as the Mayan pyramid type. We tried to find the written records of contact with aliens, but it seems that someone was deliberately erasing these records. I suspect it was the main palace, uh, there was no big progress. In fact, we thought we had found the direction of the breakthrough, but it was a pity."

"What a pity?"

"Well, an amateur history enthusiast, especially likes to study the history of the Crusades in Europe, he put forward an interesting argument, that is, the Holy Cabinet and the Knights Templar. He believes that the Knights Templar really got something when they were stationed in the Holy City, and this thing is the Holy Cabinet. He believes that the Holy Cabinet is not the Ten Commandments or weapons, but some kind of medical item with the effect of resurrection. Just like the medical warehouse, this history enthusiast seems to have really found some evidence, but unfortunately he died and all research was interrupted."

Yang Yi tried his best to calm himself down, and then he smiled and said, "It's a very interesting argument, but unfortunately it's too lack of support."
