Are aliens Reall?? Are we the only creatures in this universe?

Answer 1

The Rare Earth hypothesis argues that the emergence of complex life required a host of fortuitous circumstances. A number of such circumstances are set out below under the following headings: galactic habitable zone, a central star and planetary system having the requisite character, the circumstellar habitable zone, the size of the planet, the advantage of a large satellite, conditions needed to assure the planet has a magnetosphere and plate tectonics, the chemistry of the lithosphere, atmosphere, and oceans, the role of "evolutionary pumps" such as massive glaciation and rare bolide impacts, and whatever led to the still mysterious Cambrian explosion of animal phyla. The emergence of intelligent life may have required yet other rare events.

In order for a small rocky planet to support complex life, the values of hundreds of variables must fall within narrow ranges. The universe is so vast that it could contain multiple Earth-like planets. But if such planets exist, they are likely to be separated from each other by many thousands of light years. Such distances may preclude communication among any intelligent species evolving on such planets, which would solve the Fermi paradox.

Answer 2

So far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.

Why haven't we heard from them?

Perhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.

Perhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that just flew by may be a surveillance craft.

Perhaps they are so far away they will never notice us and vice versa.

Perhaps they existed a million years ago and died out.

Perhaps they will exist a million years from now.

It is really impossible to know for sure.

The Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

Answer 3

We certainly can be creatures or victims to our own imagination
whether it scares easily or not.Everything we seem to pro create
inour imaginative seems to stem from some fear.What kind of fear? I don't know ,but fear never the less.Maybe our imaginations just are not prepared to deal with the normally incomprehensible .Some poeple love to Imagine or theorize
that "If we are alive " Why cannot some other life be"But
the funny thing is we are surrounded by alien like creatures every day.There really are so many amazing life forms .Who is
to say or not that there are some "out there" Maybe...Who
are intelligent thinking ,creating beings or what have you as we are.
If anyone knows they are not telling."Could you blame them?"
....lol psych

Answer 4

Yes, Virgina, there are real aliens. And we are them, at least from the perspective of entities from other environments. And even if, on the off chance that this is the only planet in the universe with life forms, aren't humanoids alien to sea life? and avian life? What must other beings we share our planet with think of us?

Answer 5

Are aliens real? Probably.
Are we alone in the Universe? Almost certainly not.
Have aliens ever visited Earth? No.

Space is just too big, and there are way too many planets out there for life to develop on for us to be the only living things in the Universe.
But the immensity of space also virtually guarantees we are isolated in our little corner of it, and no one else has ever come to visit.

Answer 6

We are here and many have the suspicion that they have been also. Personally I've seen what some others would say is either proof of their existence or my need for better and stronger medications.Many people have faith in religion by just reading about it in history.Now we have videos and pictures of alleged alien beings and technologies and these same people may say it's our delusions.Someone is pretending to be someone or something else whoever they are.

Answer 7

first let me tell you that I am not crazy, although some might consider me so. My brother and I have given this a great deal of thought search and research and have come up with this answer.
I have no proof that we are the only creatures in the universe, I also have no proof that we aren't. I even think it is possible that we are them and they is us. As Sherlock Holmes said, having eliminated all the possibilities what remains must be the truth

Answer 8

I believe implicitly in Aliens - I had a close encounter when I was a teenager! For those that mock me, I say, whilst I can't prove what I saw, you can't prove I didn't.
I can understand though, how some people want to believe the world we live in is black and white, not many shades of grey. After all, it would blow their little lives to smithereens if they had to accept how insignificant we as people are.

Answer 9

You kinda answered your own question. It is hard to believe that we are the only creature in the universe. I think people say no because they are afraid of the unknown.

Answer 10

It is impossible for us to be the only people in the universe. The universe is so vast that there has to be another life form out there even if it is millions upono trillions of miles away
