My name is Yan Shunlu, and I was completely shocked by Goliath's speech, although I had been prepared for it, but these news were still shocking enough, and it was not only me who was frightened, but also a group of experts.

Goliath's words are a hammer in the east and a stick in the west, but I have to say that they are shocking enough. Every sentence is uttered with a bunch of exclamation points, which is staggering. If it weren't for a living Atlantean standing in front of him, he would definitely think that some neurotic had escaped and told a fantastical story in a serious way.

"Okay, let's reveal so much first, I'll talk about them one by one. Just like you make history books, the people of the later dynasty will do the history books of the previous dynasty, because the farther away we are, the more the historical truth will be buried, we live 20,000 years ago, and we have more say in the older history, and we are closer to that history. The Mayans left a legend about the existence of 4 civilizations on the earth, which is not a legend, it is a real existence, and we left it through the mouth of the Mayans, but it is too unbelievable for you, it is considered a legend, and this is also what we didn't expect at the beginning. ”

"In the statement we left through the mouth of the Mayans, the first generation of human beings was a giant race, and there are legends of giants in all countries in the world, and it is not strange for a people to have such legends, but when almost all countries have such legends, they often point to the truth, but you are not aware of it. At that time, the ecological environment of the earth was completely different from now. With a wave of her hand, Goliath said, and the 3D model of the earth in the air changed, and then the entire conference room seemed to disappear, and a group of us went straight to the outdoors, full of greenery, a few points bigger than the giant trees of the primeval forest.

"Don't be surprised, this is our technology, so that everyone can better understand the environment at that time, and don't be too surprised by what you see next, it's just a projection, and it won't hurt everyone. If you have heart disease or high blood pressure, please be careful, the next step may not be for you. Goliath had a friendly reminder.

After all, all the experts present are experts, the country's treasures, and they are all old, and even some are already in their old age, and the body at this age will inevitably have some geriatric diseases, and it is difficult to say that there will be a little accident, which is a major loss for the country.

I passed my worries on to Goliath, who bowed slightly at me, and then we changed again, we were still in the conference room, but the walls became transparent, as if we were going to the underwater world, as if we could blend in with the surrounding environment, but we could not touch it.

It's a Jurassic era, surrounded by towering trees that can only be hugged by dozens of people, and the animals are huge.

"Just like your archaeological discoveries, the animals that existed in this era were much larger than they are now, such as dragonflies, which are only 10 centimeters in size now, and dragonflies in this era can spread their wings up to 1 meter to 1.5 meters. There are also scorpions, centipedes, etc., all of which are several times more than the current size. Because in ancient times, the air was more abundant in oxygen, which caused all living things to be huge. The surroundings were also constantly displayed as Goliath spoke. Huge dragonflies, centipedes, scorpions, conchs, and more.

"But the Giant Clan is not this period, it will be later, this time is already the world of dinosaurs, and the time of the existence of the Giant Clan is this time." As he spoke, the surrounding scenes have also changed and become the Jurassic we are familiar with, which can often be seen in film and television works. You can still see dinosaurs, but it's just an image, no sound, otherwise it's too realistic, it will really make people's hearts unbearable, that's it, when an unknown kind of dinosaur appeared at the door of the conference room, the huge head, plate-sized eyes and sharp teeth, it still scared me, two trembling, almost want to go first.

It's that the experts' psychological endurance is much stronger than mine, seeing these ancient creatures, in addition to the initial shock, the rest is excited, looking at their appearance, I can't wait to catch them and study one or two, anyway, Goliath has already reminded them, it's just an image, it won't hurt them. What's more, the technology is so realistic that it makes people feel as if they are in that era, and the creatures around them are within reach.

If I had used this technique in my classes back then, I think my grades in geography and history would have been much better than now, and everything would have been turned into images and presented in front of me as if I had experienced it, and I would have been more impressed by seeing it with my own eyes than hearing about it.

"The giants of this era are still very ignorant, it should be said that it is equivalent to the Homo sapiens in your mouth, they still live by hunting, and they will use natural fire sources to cook food, and their food is dinosaurs. Therefore, in some of the murals left behind, we can still find scenes of humans chasing and hunting dinosaurs. It was later recorded that the giant died of starvation due to the mass extinction of the dinosaurs. The giants' main source of food was gone, and other foods could not meet their energy needs, so they starved to death. ”

"How did dinosaurs go extinct?" I asked, and this is one of the topics that people are debating, there are many theories about the cause of the extinction of dinosaurs, but there is no unified statement.

"The extinction of the dinosaurs, you have found some answers, a paleontologist and physicist from China in 2009, his team found a high concentration of iridium in the K-T line stratum of the Chicxulub crater 65,348,300 years ago, which is 232 times higher than the normal amount. Such a high concentration of iridium can only be found in meteorites in space, and the Earth itself cannot exist. According to the precise determination of the amount of iridium around the Gulf of Mexico, the material of an asteroid with a mass equivalent to Mount Everest at that time not only hit the Central American region of the earth, but also broke through the crust, and then there was a major earthquake that had never occurred on the earth. The impact threw the molten into the air thousands of meters, followed by a stray fire that lasted for dozens of days, and the heat was perhaps not the deadliest. Tens of millions of tons of dust, toxic substances spread across the globe in the following month.

For more than four months, the sun was just a vague shadow, plants stopped growing, herbivores were dwindling, and foul air, food shortages, and diseases ravaged the surviving dinosaurs. Due to the cover of dust, the earth is facing the invasion of cold. But cold doesn't seem to be the most serious problem, however, keep in mind that the sex of some animals is determined by temperature, and dinosaurs are just one of them. caused the mass extinction of this organism.

You all discuss the theory of impact of alien celestial bodies and the theory of volcanic eruptions separately, but both of these academics have considerable flaws, the alien celestial body theory is not enough to affect so severe, for so long, and so far (global), and the volcano theory, the volcanic activity on the earth itself is many and violent, but it is not enough to cause such a large extinction of organisms, including the Yellowstone supervolcano, and the direction and evidence provided by Chinese scholars 0 perfectly answer the long-term questions of the international paleontological community, It is the combination of the two that could have caused such a major mass extinction on Earth.

Of course, there are not only these reasons, but there are other factors that combine to cause the mass extinction of dinosaurs. ”

Goliath stopped when he finished speaking. The demonstration started empty, directly presenting the original scene, and now we are like receiving a popular science education.

I saw a huge meteorite streak across the sky, behind it was a long red tail caused by friction with the air, and then slammed into the ground, and then there was a violent vibration and dust rising in the sky, and huge cracks appeared in the ground, devouring the creatures that came and went. Because the meteorite was so huge, the energy of the impact was transmitted to the ground, and then it caused a violent reaction in the earth's crust, and the volcano began to erupt, and this impact caused multiple large volcanic eruptions, and it lasted for a long time, and the dust from the eruption covered the sky again, and the ground fell into darkness, and most of the world was shrouded in darkness. For a long time without sunlight, the temperature of the earth drops rapidly, and plants die in large areas, accompanied by the death of herbivores, and with the famine of carnivores......

No matter how long the darkness is, it will pass, and when the sunlight returns to the earth, it has been several months, and it can be seen that there are still many life on the earth that have survived tenaciously, but the consequences of this impact are too great, and the subsequent effects are complicated. The plate movement is also going on, the entire atmospheric environment has also changed, the emergence of small warm-blooded animals, began to seize the living space of dinosaurs, a series of comprehensive results are dinosaurs, the former overlord of the earth sang the last sad song.

The giants struggled through hunger and cold in the dark, and eventually died out with the dinosaurs due to lack of food......

There was a brief silence in the conference room, and everyone did not come out of the shock for a while.

"Then why do we find fossils of dinosaurs, but not fossils of giants?" I broke the silence, maybe I'm used to the shock.

"The giants are also humans, although their intelligence is still in its infancy, but it is much stronger than animals, they can avoid disasters, they can move, and it is because of this that most of their remains are left on the ground, which can easily be naturally decomposed and disappear. How many dinosaur fossils have you unearthed so far? And the number of dinosaurs that have existed for tens of millions of years? There weren't many giants at the time, so it's normal not to find them. "Goliath gave me an explanation, I don't know what the experts think, at least I'm satisfied.

"What about the giants? How tall is it? Social? Is it a matriarchal society? Is it in the Stone Age? Some experts came back to their senses and began to ask questions.

"We don't have much contact with the giant society, they are also a matriarchal society, they can make tools simply, haven't you found a huge ball? That's their handiwork, they are about 3.5 meters tall, and the tallest is 5 meters. “

"Wait, they're gone, leaving almost no trace, so how did you know they existed?" I interrupted Goliath, and many experts in the audience looked at Goliath curiously.

"Of course, the people before us told us, the second generation of humans after the demise of the Giants, they recorded that history." Goliath said unhurriedly.

"The second generation of humans?"

"Yes, they are called ......"
