Are We Alone In The Universe?

You can't be sure that we are alone in the universe because we are observing some 'cosmic rays' in the solar system whose origin is unknown. May be they are from some aliens because scientists are saying that they must be definitely from an 'extra-solar system origin'. But we are not able to decode them. If we have that much technology to decode them.....you'll have friends outside the solar system. The thought itself is very thrilling, isn't it?

I have a hard time believing that we are the only intelligent lifeforms in the whole universe.  Of course, I don't expect this to really be answered with proof in my lifetime, or even in the next 100-200 years, but anything could happen.

It is difficult to fathom that we are the "only"  one's in the vast galaxy...♥nassy

Personally I really don't think that we are along in the universe.  I really would like to believe that they are more intelligent life out there.  The reason that we have not make contact with them is that we are so socially selfish (well most of us, there are those who will be willing to give their lives so someone else may live).  That we are so busy fighting with each other that we do not know how to live peacefully with each other.  That is what I think.  Hopefully I did not step on any toes out there.

I do not think we are alone..There has been proof....they don't want the public to know due to people panicing..But yea I believe there is life somewhere out there...

There are more stars in space than there are grains of sand on the earth, if only even a small fraction of these stars have planets orbiting them, that's still billions of planets. To think that none of these planets would have even simple life on them is stupid. I think there is almost certainly other life out there, and I think at least some of these other life forms will be as intelligent as we are.

No one knows for sure.  Well, I suppose if we are not alone and some top government people might know this already. It is highly unlikely that in a million universes that we are the only creatures.  However, it might take a long time for them to get to visit us.  They might also think of us in the same way that we consider them.

It is said that when we realise that we are not alone, all the differences in the world should end because we have to see ourselves as the human race, as different from alien races.

Of course, they may have the same attitude as the British, French and Spanish in the 18th Century, or Germany during the Nazis, or American foreign policy.  We never know how they might consider planet Earth and its people.  They might not understand us at all and they might be planning on simply wiping out this needless world.  If this is the case, major religions will fall because we will realise there is something more powerful, and God might not exist.

The light you see coming from our closest galaxy would take 2,000,000 years to get here at the speed of light.

So when you look at that light it's from 2,000,000 years ago!

Your looking at the past, and not the right now!

So you or I don't know, Cuz

There are an estimated 750,000,000,000,000,000 solar systems throughout the entire visible universe. It makes sense logically and mathematically that we're not the only carbon-based life forms in the universe. It would be nearly impossible that we are seeing as how vast space really is.

As for the theory that aliens are visiting Earth, that's a load of garbage. Aliens are not visiting Earth, but virtually every scientist will agree with the statement that we aren't alone in this universe. Obviously intelligent life is going to be much rarer than basic life, though.
