Are we alone in this universe? Or Are we delusional?

ShardAerliss, Thanks for your response, anyway. Observing or looking at creatures on Earth (i.e., ants, sharks, bears, humans etc), it is typical that they may have a desire to invade others. Otherwise, there is no war at all. Also, take a look at science-fiction movies, why would Hollywood assume that creatures from outer space may be capable of invading us? I don't assume that it is always like that. There is always an exception, though. Since Scientists are saying that there are organic compounds drifted in an outer space, it COULD BE that those creatures from the outer space may have similar basic nature with us. I am not sure about it, though. But logically, it is, isn't it? I also don't assume that other species are more advanced than ours. I am talking about a few species which may be more advanced than ours. Otherwise, UFO won't never become such popular thing. Again, you misunderstood what I meant :-) I am talking about the planet of those UFO which has been talked by many people. Logically, their planet could be much older than Earth. Take a look at this site -- http://www.ufocasebook.com/villa66large.jpg You see... that UFO's space craft has landing legs. It seems that they are made from metal. Then, how can those creatures create their space crafts if their world doesn't have gravitation?

Humans do have intelligence. But the most intelligent people (i.e., Albert Einstein) hadn't been able to create a spacecraft in the speed of light so that we can explore the universe easily.

actually, it is impossible to move faster than light because it would take infinite energy or zero mass, which cant be done. it is theoretically possible to create a wormhole with anti-gravity which allow us to open a sort of wormhole that would connect point A and B in this universe, but scientist havent been able to do that either.

Woa.... I don't want to encounter extra terraistial life. I am actually doubtful about UFO. I'm thinking that what we're talking about UFO may be heavenly life creatures. Take a look at this video http://www.youtube.com/watch?v=KNZ2xve0zzI The shape of UFO's space crafts had been talked about since Ancient times.

Okay, if we are talking about mathematical probability, it will be possible to have intelligent creatures other places. But there is also PROBABILITY that there is also NO intelligent creature. By the way, how can Earth spin itself without anything? When humans hadn't explored outer space, they would never thought that such thing was possible.

Yes, it is so disgusting. Humans are primitive and can kill its own kind. Perhaps, that's why extra terestials are not interested in living on Earth (LOL).

Freakish! lol I've had the odd 'encounter' with UFOs. Though I'd be the first to admit that they were likely new models and designs of rather terrestrial based crafts. There is a video on YouTube of a guy filming a big, triangular black 'ship' as it glides between the clouds. There's a lot of swearing and obviously he's really freaked out by this. But, it turned out after, that it was just a prototype stealth jet, that we have all now seen. So, what you saw MIGHT have been very secret new projects... or extra terrestrials :) One can never be sure...

They got lost? lol There are so many reports of UFOs and close encounters. Some of them are obviously just mistaken... but how can we discount all of them? When I was 6 or 7 I touched a UFO. Goodness knows what it actually was, but I remember it clear as day. In fact the day was very clear; not a cloud in the sky. It was a really warm summer day, I can even remember what I was wearing. I was waiting for my parents to get ready to go out and had gone to play in the small park just outside our house. There were three yellow climbing frames there, you know the kind, made of metal poles. I was sitting on top of one, about five feet off the ground, just watching the butterflies in the laurels when a huge shadow fell over the park. I looked up to see this MASSIVE silver object above me, made of thin strips of metal with a really shiny sort of translucent sheen, like oil on water. It was so close I actually reached up to touch it. And I swear it was like... not solid, like putting your hand in water, only there were no ripples. Did I run! I ran back home yelling all the way "Mom! Mom! I touched a UFO! Mom! Mom! Come look at the UFO!" My mom came out instantly, but it was gone, utterly gone. Nothing in the sky at all; and we lived on a hill so we could see a damn long way. I don't know how much of it was down to a child's very active imagination, I don't know what it was or even have an idea of what it could have been. All I know is what I remember; and it was bizarre. If anyone has any idea I'd love to know.

Hah that's cool Shard. And yes good point. I know what video you're talking about and I know what you mean about how it could just be some kind of high-tech experiment or something of that sort. Though, I live in Canada and in a small city and if that is true I don't know why they would have been conducting these experiments or tests above this city haha. It was quite strange, either way! :P

Also, please brush up your knowledge on anatomy of the creatures on this planet, before trying to even begin to imagine what other forms of life would be like. Wikipedia could be a source of some of the information on many of the subjects.

tarachand, Although I admire what Stephen Hawking has done so far, I don't agree with all of his theories. Again, both he and we don't know exactly whether or not we are alone in this universe at this point of time. According to Wikipedia, "His scientific career spans more than 40 years and his books and public appearances have made him an academic celebrity and world-renowned theoretical physicist". Furthermore, Wikipedia also mentions "He decided to leave when he found that studying sunspots, which was all the observatory was equipped for, did not appeal to him and that he was more interested in theory than in observation" For your information, I am more interested in both theory and observation. A theory without observation is meaningless. On the other hand, observation without backing up of knowledge (theory) can also ramble around nowhere. It will also lead to a wrong conclusion. Hmmm..., I do understand your point of view. You are saying that "why should any superior intelligence have the same destructive tendencies that humans have?" My question is ... how do you know that any superior intelligence do NOT have the same destructive tendencies that humans have? Have we ever met them? Do we ever know where their planet is? From what your opinion is, it seems to me that you are very sure that our universe may consist of other intelligent creature which are NOT aggressive. The universe is unlimited. Based on the space exploration, we do know that the environment can be harsh up there. So, if you are a supporter of Darwin's theory, you will know that a creature must be "aggressive" in order to survive in a harsh environment. According to Scientist, there are organic compounds drifted in the outer space. If so, it means that other intelligent creatures can come from the same origin as humans. Take a look at lions, tigers, bears, etc. They are aggressive animals. Most animals are wild and aggressive. If they are not categorized as aggresive animals, they can be classified as wild and low creatures (ex. chickens, birds, etc). On Earth, it is ONLY human which can be categorized as an intelligent creature. Isn't it possible that other creatures in outer space are not as intelligent as humans? Is it possible that they are also aggressive?

freak369, But don't you think it is possible that there are NO other creatures in this universe? Well, my opinion can sound a bit silly. However, are you sure that there is a life in other planets? My question is... if God wants to have other creatures in other universe, why can not He place them in the planet near our Earth?

Aussies2007, 1) But human's logic can be inadequate. How can Earth spin itself without anything? Before exploring outer space, humans would never imagine such thing. 2) I think UFOs and aliens are heavenly life creatures. Bible mentions that God not only creates creatures on Earth but also other heavenly creatures (i.e., ghosts, evils, etc.) 3) No, UFOs and aliens have existed since thousand years ago. Please take a look this video "Ancient UFO Paintings" -- http://www.youtube.com/watch?v=KNZ2xve0zzI 4) I don't know why they would invade us. Perhaps, I have watched science-fiction too much (LOL). But anyway, Aliens may not be interested in living on Earth because we are primitive and barbaric. Who knows what they are thinking? (LOL). 5) How do you know that every planet has gravity. Have you ever visited every planet? (LOL).

1) Who said I am human? My logic is infaillible... Don't question it... 2) So I was right all along... God is an astronaut... 5) I don't need to visit every planets... I have a telescope and a degree in physics.
