Does life only exist on this one planet and nowhere else in the entire universe?

If life does exist beyond earth, how abundant is it?

Are there advanced civilizations thriving on other planets? How many?

Could there be other human beings living on other planets somewhere, who are unaware of our existence and awaiting discovery?

Have we been visited by advanced alien civilizations?

Were the ancient gods in prehistory alien civilizations?

How large is the universe? Is it truly infinite?

Are human beings ready to face whatever is out there?

If alien civilization openly visited us, how would you react?

If given the chance, would you go with them to explore the universe?

[Chuck]

The term is probably not appropriate for this subject, but I'd say I'm "agnostic" on it.

[Vicky.]

I think its pretty ignorant to think that our planet is the only planet with some form of life :/

The idea of that is actually quite ridiculous to me.

[Grimnir]

We live in the Milky way galaxy.

There are approximately 200-400 billion stars inside the milky way.

If you travelled at the speed of light it would take about 100,000 years to get from one side to the other.

Nearest major galaxy is Andromeda.

There are approximately 1 trillion stars inside andromeda.

If you travelled at the speed of light it would take about 2,500,000 years from Earth to Andromeda galaxy.

As well as Milky way and Andromeda, there are more than 170,000,000 galaxies in the known observable universe.

Each galaxy contains billions or trillions of stars.

Wonder how many planets exist in the known observable universe?

Wonder how many planets exist in the unknown unobservable universe?

[Chuck]

I need to be high to think about how amazing the universe is, I'm only drunk tonight

[Saph]

I love aliens I watched a program a few weeks ago which said aliens visit our planet every so often and UFO sightings are more common just before either a war happens or a natural disaster. I thought that was quite intresting, made me wonder if they're just watching us suffer for abit of light entertainment lol or if they are the ones causing these things.

They might even be us from the future looking back in time at how the world use to be I remember seeing a Family Guy ep where in the future, they take holidays back in time instead of around the world so maybe that happens for real and in 100,000's of years we look back at historic moments in time...

[CharlieO]

Yes, what are the chances that this is the only one that can inhabit life. There is life out there somewhere its just wether we can get to it or not.

[Doogle]

Yeah but I doubt we'll ever find anything.

[Livia]

Given the odds, it's unimaginable that we're the only ones amongst the billions of trillions of stars and planets out there.

It's only a hundred years or so that we've flown, and in that time we've gone from the Wright Brothers to NASA. We've come an awful long way in a very short time. Who's to say in the centuries to come someone won't come up with the technology that will allow us to travel across the galaxy and beyond? Two hundred years ago - the blink of an eye in the scheme of things - the idea that we could travel to the moon would have seemed like total fantasy. Other civilisations on other planets may be millions of years more evolved than us. Who's to say they haven't already developed the technology that's allowed them to visit us?

[Ninastar]

There has to be if you think about how huge the universe is

[Niamh.]

I don't see why not, it'd be pretty vain of us to assume we're that special really

['Conor]

possibly, but i don't believe in the stereotypical Alien **** in flying spaceships

[InOne]

Any idea we have about "aliens" has been created by man, a bit like God

True, unless they really do have some in area 51

If they did, I'm sure we would have found out by now

maybe, maybe not

[Conor]

Depends. The I think their is a possibility that there is bacteria on planets maybe even a couple of solar systems away from us right now. I'm not to sure advanced civilisations are really that common though. There could maybe as as few as couple of hundred, spread the wholeway throughout space, meaning contact is virtually impossible. But then it's also possible that there are millions of planets with some kind of advanced lifeforms (whether its similarly advanced to an insect, right up to a person) You could also ask the question of whether we are the most advanced species in the Universe. Theres no reason not too, because it is a possibility. Theres the fact that the universe is billions of years old. In that time it's perfectly possible that millions of different kinds of lifeforms have come or gone. I don't believe we've ever been visited by aliens though, even if they were 100s of thousands of years more advanced than us, I still doubt anyone is able to travel from one end of the Universe to another, and even if so, there's no reason why they'd visit us over the possible other thousands or even millions of planets that sustain life. I also don't believe they look anything like us either. Why should they? I would bet that they'd be unrecognisable and many people could probably walk past one without realising that it's actually a living thing. Of course if the conditions on the planet they came from were similar to Earths, then they would look vaguely similar.

Planet Jedward.

TBF we probably WILL find Aliens/Living Creatures on other planets eventually, I just hope it happens when I'm alive and around the age of 20 - It's my dream to date a hot purple Alien, as I've expressed a few times on here.

[Grimnir]

bet she likes dirty telepathy

[Legend killer]

ET nuff said

[Callum]

I'd like to think so, yes. I really don't see how there couldn't be to be honest, the universe is enormous.

[Grimnir]

Imagine if there are sub-atomic particles so small that from their perspective, the one single atom they reside in is the equivalent of how we see the universe

What if our universe is just one cell of a huge living creature, or imagine if it is just one "atom"

[Tom4784]

It'd be foolish to assume that we're the only life in the universe when we know so little of it. I reckon there's life out there but we'll never encounter it.

[Joe.]

Definately yes. Infact when I was 11 I was walking through a wood and kept seeing strange green lights in the sky, to this day I believe that was aliens. We are not alone. There may be many species out there which one day I hope we discover!
