This is called Fermi paradox. From pure speculation, we can think of several answers. The best thing is that intelligent life is extremely rare. This phenomenon may be attributed to the self-filtering effect. Basically, before it can send a strong radio signal to the universe, most life will destroy itself. If so, then we are very special and very lucky.
There is a lot of evidence here.
Unfortunately, none of them are ideal evidence.
People are always confused, and even the testimony of an honest witness can't completely reproduce the facts. Photos may be fake, especially now. Even the video can be faked today. The field of home computer picture rendering is often used in fan videos.
Some people think that the existence of some animals, such as killer whales and elephants, proves the existence of other cultural life forms and is similar to us in IQ. Personally, I think that based on their intelligence, they should be given the same social rights as human babies. However, this does not mean life outside.
If there is a reasonable explanation based on contemporary science, then scientists will say that it is almost certainly based on a common explanation. The golden statues in South America look like flying machines, but in fact they can fly. So are they based on alien spacecraft or local catfish? Scientists will say catfish, because it conforms to aerodynamics, which is a characteristic of fish body conforming to fluid dynamics.
Personally, I think the best evidence at present is the controversy about' Oumuamua'. Dr. Avi Loeb published a paper saying that because he does not conform to any natural contour, he does conform to the contour of a large metal plate. Therefore, logically speaking, it is a heterogeneous metal sheet.
Which one is it? There are two types, and you can find the answer from the following.
Two main types of aliens (intelligent extraterrestrial life)
answer
Humanoid creatures like us were born on the planet. There are 5.4 trillion planets for your reference, distributed in seven hyperuniverses, including the Milky Way, and now they are hovering in heaven. But this is really just the beginning.
b)
Entities created by God or our Christ Michael, like your guardian angels or life carriers, prepare DNA for every planet they want to implant life into.
Class A) can't come here, while class B) is like your guardian angel around us, but we can't see it.
What is the evidence of other alien life forms in the universe?
Arrogant human beings.
Open your eyes and use a magnifying glass if necessary.
It has long been known that ants are agricultural animals, millions of years earlier than humans. They graze aphids and feed them. Looking up, you can continue to talk about octopus and dolphin. It will only come to you as soon as possible, but realize that it needs greater wisdom than you.
If the crazy stories about UFOs, appearance kidnapping and Roswell are excluded, one incident may be attributed to.
Alien intelligence. Wow signal
1On August 5th, 977, the wireless telescope of Ohio State University detected a powerful narrow-band radio signal, which seemed to come from Sagittarius. The scientists who detected this signal decided to call it the Wow signal.
Despite many attempts, it has never been observed again, and today it is still a candidate for powerful shape signals.
However, not everyone is convinced. Some people think that this signal is a land signal, and it is a signal reflected back to the ground.
The year before last, astronomer Antonio Paris and his team theoretically explained that the Wow signal was generated by a comet, but not all scientists agreed with this statement.
In some of the most traditional desolate areas on this planet, the emergence and prosperity of life is evidence that there may be another world under the ice or deep underground in Europe. Mathematical calculations seem to support this statement, just as we now know that most star systems have planets.
It's hard to imagine how a life without evolution evolved from technology, but it's hard for ordinary people to think outside our thinking frame. It is conceivable that a class of creatures can evolve without a quantum field, in which distance is invisible. In this case, we may have a difficult event to identify it and accept the challenge!
