Have aliens ever been to Earth? What records of ancient civilizations have scientists found?

Aliens have not been to Earth. Although scientists have found some records of ancient civilizations, these are unrealistic and have no scientific basis.

The alien should have never been to Earth, because he did not leave any elaborate information, so this is just an inference from scientists.

Extraterrestrials have always been a hot topic of discussion, and speculation about extraterrestrials is endless. From ancient times to the present day, there have been many records of suspicious aliens arriving on Earth. In recent years, there have been many UFO incidents.

However, many of them are nonsense, completely fictitious, and there is evidence that most of them are artificially faked. So far, no conclusive evidence has been found for the existence of extraterrestrials. Some are hypothetical, some are UFO finds unrecognizable**.

Since the 1960s, humans have planned to search for extraterrestrial life and extraterrestrial civilizations. By now, more than half a century has passed. Humanity still hasn't found anything in the vast universe.

Finding an alien civilization is like looking for a needle in a haystack, so have aliens ever been to Earth? From some records and artifacts of ancient civilizations discovered by archaeologists in recent centuries, scientists say that perhaps extraterrestrial civilizations have actually existed on Earth.

Are humans the only intelligent beings in the vast universe? No. Our technology can't even understand 10,000 meters of ocean floor.

Moreover, there are no advantages. I can't imagine how big the universe is. Since humans cannot be the only intelligent beings in the universe, have there been any aliens to the Earth where we live?

No, that doesn't mean it doesn't exist. There are some miraculous records in ancient books in our country. At that time, people didn't know why or why.

But now, it seems that aliens have arrived on Earth.

According to the Southern Song Dynasty Robbie's collection of ancient history, geography, customs, clans, legends of the book "Lü Shi", after the establishment of Pangu, there were 13 brothers of the emperor's family, in the South China Sea, named Pangu Kingdom, the emperor's head and scales, that is, the human head and snake body, with dragon horns on the head, different from ordinary people, are governed together. So, what is this atmosphere that can filter out Japan's toxic rain? Isn't this the ozone layer as we know it now?

That is, the ozone layer is ancient. After the heaven and earth were opened, the emperor's family brought people to build it. In addition, the emperor's so-called "knots" and "scales" were not like humans, and they could still rule the world for more than 28,000 years.

There is reason to suspect that in ancient times, aliens may have visited Earth, and they also modified the Earth's natural environment. Of course, only the record of the "History of the Road" does not say anything. If you look up, there is a wonderful book of prophecy from the Han Dynasty called "The Preface to Life in the Spring and Autumn Period".

There's also a very strange content on it. What is it? After the emperor's family, there was an Earth monarch who ruled for 36,000 years.

After the king of the land, there was a family of emperors, who ruled for 16,500 years. This is the legendary old Huang San, different from the Huang San of the Three Emperors and Five Emperors we know, earlier than them. After the imperial family, there is the imperial court.

Although the Titing family is not as magical as the emperor's family, it still has considerable ability. <>

There are two very different views on the existence of aliens, but the universe is so big, I think there must be aliens, and humans have not yet come into direct contact with aliens.

It doesn't exist, many of it is hearsay, and I personally think it's more true to see is believing. A lot of the rumors are based on a speculation about the unknown world that has no factual basis.

I think that alien civilizations are real, and aliens may have come to the earth, but the current technology developed by human beings is limited, and no traces of them have been found for the time being.

Exist! And have already visited Earth! Although there is no conclusive evidence, the universe is endless, and there are too many places that humans cannot reach, and there are many unsolved mysteries at present.

The existence of extraterrestrial civilizations is inevitable, after all, the universe is so huge, there will be many planets suitable for living creatures, but it is difficult for human beings to detect with existing technology. It is difficult to confirm the authenticity of the aliens visiting the earth, but there are really alien civilizations that are more advanced than human civilization, and it is not impossible to visit the earth.

It's possible. Many inexplicable buildings, some artifacts that have just been unearthed but are obviously out of place, may be proof of the arrival of extraterrestrial civilizations in ancient times.

There is no scientific confirmation of this problem, and extraterrestrial civilizations that can reach Earth have not yet been discovered.

This is possible, because the universe is so large, it is very likely that there are highly technologically advanced alien civilizations that have been able to travel through the universe, and it is possible that they came to Earth in ancient times.

It can't be, because there is no extraterrestrial civilization in the universe at all, there is no scientific basis.

In fact, for us, many scientists now speculate that extraterrestrial civilizations seem to have played with the earth in ancient times, and left behind the previous civilizations, so this is also a certain possibility for us.

It is possible that extraterrestrial civilizations have already visited the earth in ancient times, because in such a thick atmosphere, why did there exist cells on the ancient earth and then derive us? So, it could be that aliens brought us to Earth.

No one knows if there is intelligent life other than human beings, and if there is an extraterrestrial civilization that has come to the earth, then their civilization must be more developed than the earth civilization. The universe is huge, and there is no historical record of whether aliens have ever been to Earth, and no one has seen them, so we have no way of knowing whether they have ever been to Earth.

I think before the birth of mankind, extraterrestrial civilizations came to Earth. Because if the aliens hadn't come, those aliens wouldn't have stayed, and if there were traces, they would have been.

There is no way to judge, because human technology is not particularly advanced, so aliens and extraterrestrial civilizations cannot be confirmed.

Mayan culture, pyramids, etc. cannot explain them with current technology, and some even use modern technology to make a replica. So now there are some theories that they got help from aliens, but for some reason they evacuated the earth, but they still watched the earth from afar.

No. Because the probability of the birth of extraterrestrial life is almost equal to zero, and it is impossible to come to Earth, extraterrestrial civilizations have not been to Earth.

The ancients put forward various conjectures that are round and circumstantial, and gradually unveiled the mystery of the planet we live in through step by step confirmation. After unveiling the Earth, our research expanded to explore other planets. At the moment, we are looking for civilizations on other planets besides Earth.

It is very likely that there are many undiscovered places in the world, and there are some strange buildings, most likely built by aliens.

Not really. Because aliens do not exist, and it is impossible for an alien civilization to hit Earth, this is not true.
