Yes, there may aliens too, but there are millions of visible and invisible species living with us too.
Astronomy is discovering more and more life-bearing planets in the universe, raising the likelihood of life elsewhere, although too far away for known space travel. If a greater understanding of time evolves and that can be utilised, according to recent investigations, then maybe we can all meet up in some United Planets of the Stars.
نحن لانعيش وحدنا في هذا الكون فهناك العديد من الكائنات والمخلوقات غير المرئية
There are 100 billion stars in our galaxy alone, and there are 100 billion galaxies in the known Universe. The number of stars in the heavens are more than the number of sand grains on all the beaches of the world put together. So high possibility of life evolving somewhere else too.
Dear Zeinab,
You sure know this intriguing question has been asked by every living human being (at least to himself), since the first grandfather (Adam). The modern sciences and radio microscopes are giving us more questions than direct answers (e.g., the anti-matter world, black holes, neutron stars, ...etc.). However, the smart unbiased brains should predict (and can realize) that we are not alone. There exist many unseen creatures all over the seen and unseen world(s).
Nobody is alone in this world . Society , Friedship , Wife , Spouse not all case will
remove lonelyness . The parents who will only absorb your loneliness .
Yes, of course, and with a high degree of confidence, we live alone in this universe, and I do not think that there are any aliens living with us in this large and vast universe.
I think we are not alone in this universe but the thing why we are not seeing aliens yet is because we assume them a human being but with ugly bodies. Actually, they could simply be bacteria, insects, viruses, or even anything else.
Do we live alone in this universe? Do you think there are aliens?

Answer to the first question:
There was a well known Russian astrophysicist Iosif Shklovsky who wrote a book about out-of-Earth civilizations. First, he stated there are no any particular information / signals that would put this question into a practical perspective. Nevertheless, he analyzed necessary physical, chemical, and biological conditions that would enable a development of a human-like civilization. Eventually, he came to a conclusion that the probability of meeting all those conditions at any particular place is very low. It doesn't mean it's impossible, but the expectations are extremely low.
Answer to the second question:
My guess is as good as anybody else. According to the said above it's rather no than yes. However, if our civilization can keep piece on Earth, humans can begin exploring and exploiting some close to us planets and their satellites. So that in a historically small time interval we may have human colonies in the close space. That seems like a very complex but doable goal, if humans' civilization can get united and pull resources to follow on this interest.

Shklovsky's book:
His 1962 book, Вселенная, жизнь, разум (Universe, Life, Intelligence), was expanded upon and reissued in 1966 with American astronomer Carl Sagan as co-author under the title Intelligent Life in the Universe (1966). This was the first comprehensive discussion of this field. Discussing the biological as well as astronomical issues of the subject, its unique format, alternating paragraphs written by Shklovsky and Sagan, demonstrated the deep mutual regard between the two and allowed them to express their views without compromise.
It is impossible living alone. In society, there is interdependence.
ResearchGate is so weird. I just boosted my score with a meaningless response to a question about aliens.
i believe there are jin ( jinnat ) on earth which are invisible whereas possibilties of existence of other creations like so called aliens is not yet ruled out.
it has become official since the US Navy endorsed (and allowed ) the release of these videos off the California coast. In the past if you worked for the USA Army you could not release any information without losing your life. Now, such information has become commonplace. Anyway, there are more than 3 million sightings of UFO's since the 1940's with pictures, stories and now videos as well. Do you think all these witnesses are hallucinating? I am glad I have seen such amazing technology that does not belong to humans and it was brought over to EDUCATE us.
Si es seguro que tienen que existir extraterrestres, incluso más desarrollados que nosotros en todos los campos. Respetuosamente. Rodolfo Vega Candelario.
we are not living alone, jin,animals,birds,insect and microptera are all living with us. they are nations like us.
It can't alive alone in the univers, by I think it is seldom to find real alliance.
We think there may be 3 different types of civilization in the Universe. This is called the Kardaşev Scale.
Type I: A civilization that has the power to use all the energy of the planet in which it lives. We are in about 0.73 of this scale. We are now in the transition from Type 0 to Type I civilization, and maybe we will become Type I civilization in 100 years.
Type II: A civilization that can use all the energy of its own sun. This means achieving an engineering that looks like science fiction but is possible in theory (eg building a Dyson Sphere that surrounds the Sun).
Type III: A civilization that knows the galaxy it is in as well as the back streets of the neighborhood and can use its energy source in every corner of the galaxy.
Are we the only creatures living in space, which seems to have a diameter of 93 billion light years (approximately 93,000,000,000 x 10,000,000,000,000 km!)? There are two trillion other galaxies in the Visible Universe. There may be hundreds of billions of stars and trillions of other planets in each galaxy. This increases the likelihood of other creatures in one corner of the universe.
