"Today is a historic turning point in human civilization."

　　 "At 15:46 today, NASA organized a paleontological fossil excavation team to Mars. In the foundation tunnel of a Mars base, a large number of neatly arranged human-shaped skeletal fossils were successively excavated."

　　 "In order to answer some of our questions, we invited Professor Huogu, who is located at the International Astronautical Center to remotely direct the excavation work."

　　 As soon as the host’s voice fell, the screen changed, and the host’s interface changed to a small window. An old man who looked elegant and easy-going, in his sixties, appeared in front of the public.

　　 "Hello, Professor Huo Gu." The host said.

　　 "Host, hello." Huo Gu said.

"Professor Huogu, can you tell us about your latest research progress on the humanoid skeleton fossils excavated on Mars? Now it can be said that the entire world, as long as there is an Internet connection, is paying attention to this matter. "

"Ok."

　　 Huo Gu nodded slightly, and said, "In order to ensure the integrity of the fossil group and to obtain more information in a short period of time, we specifically excavated a human-shaped skeleton fossil."

　　 "From this, we can also conclude that we humans are not alone in the universe."

　　 "Because they are Martians?" the host asked.

　　 Huo Gu shook his head.

　　 "No, the owners of these humanoid bones are not native Martian creatures. They come from other planets and belong to another ecosystem besides the Martian ecosystem."

　　 was shocked, and the host’s eyes were obviously wider than before.

　　 The breathing and tone of support for people could not help but become a little rushed, and said, "Then, which planet do these human skeletons come from? What is the evidence for this conclusion?"

Huo Gudao "Although there are many kinds of life on the planet, as long as you look back to the source, you can find that they have the same ancestors along the evolutionary route in the past. Those of us who study'Martian biology' call this species at the source of evolution 'Cornerstone Species'."

　　 "This... can you make it a bit more popular?" The host looked a little embarrassed.

　　 "Take the earth as an example. The early earth environment was transformed into an oxygen environment. After that, the mainstream of the earth's biosphere was to consume oxygen to sustain life activities."

"The same principle applies to Mars. The mainstream of Martian paleontology is the'exoskeleton'. The bones wrap the organs and support the skin and muscle tissue. Under this system, if there are Martians of the same size, it is better than Normal people are 1.5 times heavier, but those human-shaped skeletons are not like that. Their skeletal structure is more similar to that of life on Earth."

　　 "It turned out to be like this."

　　 The host nodded in a daze, and didn't know if he understood.

　　 "So, were these Martian fossils intelligent life?" the host asked.

　　 "I can definitely answer this question, yes." Huo Gu replied.

　　 "Each corpse is arranged neatly, forming a huge group of square fossils, which is very similar to the ‘burial’ on our planet."

　　 "From this, we speculate that they are wise and not low, at least they are in the Stone Age."

　　 Suddenly, the host's complexion condensed, and he listened very carefully for a while while pressing the headset with one hand, and then asked.

　　 "Professor Huo Gu, there was a problem on the Internet just now. The number of hits exceeded one billion in an instant, and it is still rising rapidly. Can we ask you about this?"

　　 "Of course." Huo Gu answered with a smile.

　　 "What do you think of the ‘crossing’ thing? Is it possible that these humanoid bones were the ancestors of humans who crossed to Mars?"

　　 Huo Gu shook his head with a smile.

　　 "No, it's impossible. I just said that it is similar to earth creatures, but I didn't say that they are consistent. The owner of the bones and earth creatures are not the same system.

　　 So, a picture appeared on the lower right side of the screen. The bones are quite similar to human bones. One of the few obvious differences is that there is a hole in the forehead.

"We can see that there is a hole in the center of the forehead of the skeleton, which is not caused by the damage of the skull. According to the results of our computer's comparison of the intracranial structure, we found that the structure of this hole and the other two eye sockets are basically the same. From this we infer, This hole is an eye socket."

　　 "In other words, the owner of the skeleton is a humanoid creature with three eyes."

　　 "Like what I said just now, the ‘keystone species’, from the initial birth of earth creatures to the present, no species has three eyes."

　　 "In addition, the Mars excavation team did a simple atomic decay cycle measurement. The fossil bones existed for more than 200 million years. At that time, the dinosaurs were still ruling the earth."

　　 "But these bones are too similar to human beings, how can you explain this? Is this too unbelievable?" the host asked unwillingly.

"There is nothing similar in bones. As long as you compare them carefully, you can easily find the two bones. Except for the forehead and eye sockets, the bones of humans and chimpanzees are also very similar. Are the appearances of humans and chimpanzees too similar to distinguish? "

　　 Huo Gu hesitated for a moment, and then replied.

　　 "Host, I do have some opinions about ‘crossing’."

　　 "Please tell me."

　　 The host suddenly came to the spirit, UU reading www.uukanshu. Com's eyes are piercing.

　　 "Before that, let's assume that'crossing' is a true proposition."

　　 "We all know that the universe is very large and very large. The observable universe alone is 93 billion light-years in diameter, and our Milky Way is also very huge, with about 100 billion stars."

　　 "Then there is our solar system. If defined by the celestial planets, the average radius is 82 astronomical units. That is to say, if you use me as the unit of measurement, approximately 12.3 billion me can be filled."

　　 "In addition, the positions of celestial bodies are constantly changing. Our home star is revolving around the sun at a speed of 29.783 kilometers per second all the time."

“It’s hard to imagine that this kind of traversal will happen on the earth so coincidentally, and, even more coincidentally, among many earth creatures, humans have been selected as the objects of traversal. After the traversal is successful, it can ensure the maintenance of the most basic life activities. , It’s an incredible coincidence."

　　 "Professor Huo Gu, you... don't like the existence of'crossing', right?" the host asked.

　　 Huo Gu smiled irresponsibly.

"how could be?"

　　 "In probability, the probability value of things that haven't happened is never 0. Maybe someday in the future, there will be such a person. He has passed through, just like in the novel."

　　 "What I want to say is, if a crossing does happen on a certain day, I am more inclined to think that it is a man-made event, an event triggered by the subjective behavior of an unknown civilization in the universe, rather than because of some accident..."

　　 "Professor Huo Gu?"

　　 The change happened so suddenly that the host was caught off guard, and it took a long time to react, and he turned his head and shouted in disregard of the image.

　　 "Hurry up and hit 120!"
