If extraterrestrial intelligent life exists, how large might they be?

It may be very small, it may be very large, it may be that both of them have aliens, which are generally more mysterious, in fact, in the eyes of aliens, we should also be considered aliens.

Judging from the proverbial saying that one mountain can't tolerate two tigers, there will be no humanoid aliens in the universe to which human beings belong, so is there any alien matter in the universe where human beings appear, and is it **! This requires human beings to explore, to discover, and it is very likely that they will find many strange bacterial spores, virus spores, and so on!

The volume should be very unimaginable to us, and extraterrestrial life also has its own living space and its own way of communication.

I think that if there were extraterrestrial intelligent life, they would probably be about the same size as us, and they would probably need food and water for their daily lives.

The existence of extraterrestrial intelligent life has always been debated in the scientific community, and the size does not matter, the point is that their abilities and intelligence will make us afraid.

They may be very small in size, often much smaller than humans, but they are also an intelligent population, and they are worth exploring by people.

For this question, we can boldly speculate that human beings were very small creatures in the past, and gradually developed, so whether aliens are the same as human beings, they are also constantly developing, but their development space is different from ours, maybe like us humans, maybe bigger than us, maybe smaller.

Probably tall, have you ever seen Ultraman? It could be that big.

There are intelligent beings outside the universe, and they no longer visit the universe in person, but send reconnaissance vehicles to probe and regularly understand and study them. The survival of the earth's civilization may be that the galaxy is on the edge of the cosmic desert, or it may be that other planetary civilizations have fled here, bringing the source of species to the earth, transforming the earth for tens of thousands of years, and finally re-establishing a new home, the moon is their means of transportation to escape from their homes, and the moon is used as a base when transforming the earth and its surrounding environment, driving away the meteorites that block space.

Their size should be about the same size as that of human beings, not that the larger the volume, the greater the intelligence, it mainly depends on the actual situation.

They may be larger than the sun alone, and the earth is just a roar of their bodies.

If there were extraterrestrial intelligent life, they would be very large.

The history of mankind is too short in the universe, will we be alone? With the redevelopment of science and technology, it is not difficult to artificially transform a habitable planet. The universe is infinite, and the advanced civilization can't look down on the earth, so it's better to develop yourself with peace of mind, right?

Foxes are very cunning, cows can shed tears, dogs will watch people put down dishes, it doesn't matter if the size is the key, the key is their wisdom.

I dare to guarantee that there will be no aliens in the universe, and if there is, either we will find them, or they will find us, and there will be no ** on the moon and Mars.

The height of alien vital signs should be about meters according to my visual observation of the height of the flying saucer, only the middle has a height, and the edge cannot accommodate life, and in addition, they are good friends of mankind. Don't believe those who slander aliens, they're copying.

The volume should be large or large, small or small. Grab a mountain casually and fall far away.

If you sleep on the earth, the United States is the seat, and the Pacific Ocean is the footbath.

I think he should be similar to the mention of humans, because compared to the universe, it would be inappropriate for her to say that I am a little bigger.

Is the air ,,, carbon dioxide different on alien planets? Is carbon dioxide after diamond burning, the same as carbon dioxide after diamond burning, graphite, carbon fiber, graphene, and herbs after burning? Whether the plant is re-harvested or not,

Aliens tell earthlings the ultimate secret of the universe. Everything is set up. Can't play... The universe is virtual, what is the meaning of life?

On Earth, when there is enough oxygen, the body is huge. Aliens don't know.

Different living environments create different life forms! Perhaps, the creatures of a certain planet are as big as dinosaurs and much smarter than humans.

It should be the size of an 8-year-old child, because at the age of 8, the head is large and the body is small, and the brain is large.

Like Avatar, more than three meters.

Let's focus on the Earth first. Once upon a time, the earth was barren, and most of the earth was devoid of any life.

In another 1,000 or 5,000 years, there may really be aliens on Earth, and in 5,000 years, aliens can really travel the universe.

There are so many planets in the universe, and there is a possibility that they are exactly the same as the earth, the earth can evolve life, and they must be able to, and if they can't touch it, it's speculation after all, who can say, alas! It's annoying.

I think maybe less than a meter of the villain.

It depends on what kind of planet they live on.

There may be many forms of life in the universe. Our current definition of life is: That is, the phenomena of self-growth, reproduction, feeling, consciousness, will, evolution and interaction, including the amino acid structure that can be replicated by biochemical reactions, as well as fungi, bacteria, plants, animals (humans), and others will artificially send a phenomenon with a certain connotation in line with the basic attributes of life into the category of life, including hybrids, artificial intelligence robots with pure free will, etc.

<> and when we look at the universe on a larger scale, life may be different, and life may take shape beyond what we currently imagine. Take the earth human beings as an example, everything is designed according to the original materials of the earth human beings, eating, wearing, using, playing, etc., through practice, some are reasonable and perfect, but I am not close, some people are alive, not forever, such as human height, almost not long, human teeth, only one mouthful, falling, and people's **, beautiful when young, wrinkles when old, yellow, etc., although human beings are not satisfied with these, but there is no good way for the time being.

There are some ways, but we must achieve advanced civilization and use high-tech means to create the achievements that human beings need most, in order to solve the shortcomings of human beings, meet the needs of human beings, and finally start interstellar travel and fly out of the galaxy, why fly out of the galaxy, because it has not yet been discovered that there are aliens in the solar system, there is life, and it may be as long as human beings, because they belong to the solar system. The Earth and the solar system we live in are actually very small in the universe, and the number of stars and planets in the universe is staggering.

So big that somewhere in the universe there may be planets that are very similar to Earth, and there is a good chance that such planets will support creatures closer to us. But this probability is still relatively small. The biological form of the virus may have existed since the beginning of the earth's existence, and it coexists with the host in its simplest and most efficient form, and constantly adapts to the new environment through its own adaptive mutation.

We can't look at extraterrestrial creatures, especially intelligent life, from the perspective of earthlings, who may be able to survive without oxygen, without food, and only replenished by special energy.

At present, human scientific research has not found extraterrestrial life, and the Earth is still the only planet with new human figures. As for whether aliens are highly intelligent creatures, it is uncertain.

Life produces advanced intelligence, there is no growth and resilience system, there is no specific excitation conditions from the outside world, and its evolution process cannot be realized with a single or lack of a certain condition, and life produces advanced intelligence, which is not inevitable, but a single and accidental event, and life on earth has also proved this. The universe or intelligent life is almost zero.

Aliens must be humans. But extraterrestrial life is not equal to intelligent life.

Human beings are the name of the earth, and they should be called high-level intelligent beings.

I think such a claim is possible because there is no direct evidence at the moment.

There are people outside the world, and there is a sky outside the sky!

I'm not sure there is, just hear from you.
