To recon that those who don't believe alien species have visited the earth are just kidding themselves and scared.

[AgentZigzag]

And I don't mean the snoring/dribbling species sat next to you

We don't know that much about the universe, but the little 'we' do know I recon shows that the probability of other species existing on other planets is more than likely.

If you took it that the number of galaxies we can see at the min has been estimated at 50 billion, and as a conservative estimate doubled that to include the ones we can't see yet, that'd give us a hundred billion galaxies in the universe.

If you said there were about 100 billion stars per galaxy (give or take a couple of billion) and timesing that by how many galaxies there are would mean there's 10 thousand billion, billion (or sextillion) stars.

If what the scientists believe isn't true, and stars that have planetary systems are rare, and just one star in every million had planets orbiting it, that would give ten million, billion planets in the universe.

If amongst those planets, ones that are able to support life are also pretty rare, and only one planet in each million can support life, that'd give us ten billion planets in the universe that can support life.

If you think of how much our technology has developed over the last 100 years, I don't think it's too far a stretch of the imagination to think that the technology of a species that evolved a thousand/five thousand/50 thousand years (I mean what are those time periods when compared to the age of the earth?) before us, could have come up with something in that time that would get them to us?

I've never seen a UFO, or encountered anything weird, but I know that if I did I would be shit scared, so I'm not saying that people who don't believe they've visited us are big girls blouses who just can't face up to the truth.

But I wondered how you're able to ignore the vastness of space and the fact that if we can exist, why wouldn't others?

And why wouldn't they want to have a peek at us to see how we organise ourselves and whether our cakes are worth the bother of a visit?

To me there's more proof they exist than proof they don't...isn't there?

(It might look like I'm donning a hard hat, but it's actually a technologically advanced helmet that'll protect me from buns their weirdy alien thought experiments, good innit )

You don't know what they get up to when you're tucked up in bed ilovemyhens, <a class="break-all" href="http://www.google.co.uk/imgres?imgurl=1.bp.blogspot.com/_cuNe_A_U-9g/SK3Q67_y6zI/AAAAAAAAAfc/0iGRbFSiQLI/s400/FarSideCownCar.gif&imgrefurl=projectchristopher.blogspot.com/2008/08/ode-to-gary-larson.html&usg=__O9exE8N5M6WO0yRG55V3qGUlbps=&h=400&w=327&sz=136&hl=en&start=0&zoom=1&tbnid=qioO4Ghn9Ow5QM:&tbnh=124&tbnw=101&prev=/images%3Fq%3Dgary%2Blarson%2Bcows%2Bcar%2Bcartoon%26um%3D1%26hl%3Den%26sa%3DN%26biw%3D1146%26bih%3D694%26tbs%3Disch:1&um=1&itbs=1&iact=hc&vpx=125&vpy=56&dur=565&hovh=124&hovw=101&tx=99&ty=118&ei=susoTeW6LJSDhQfquriiCA&oei=susoTeW6LJSDhQfquriiCA&esq=1&page=1&ndsp=26&ved=1t:429,r:0,s:0" rel="nofollow" target="_blank">I mean just look at cows plot against us when we're looking the other way...

They could have set out hundreds of years ago in their tiny spaceship and just grew food and carried on breeding. They wouldn't be first generation.

I have a goldfish who's doing a physics degree I try not to feel jealous, but it's difficult

I couldn't give a fuck

I bet they've seen us and gone, "Urgh, no thanks". And continued on their merry way, not really fancying probing anyone.

If there are ten thousand billion billion stars, then that's a blody lot of planets for the aliens to visit - what are the chances that they happened upon ours?

I should clarify - I couldn't give a fuck if the OP thinks I am either kidding myself or scared because I don't believe aliens have visited earth

Which is an altogether different argument about life elsewhere in the universe.

Gabby, is that you?

Why would any other civilization advanced enought to travel those kinds of distances (assuming it were possible) give a crappy self destructing species like ours even backward glance? We would probably be the equivalent of primordial slime to them. Hardly worthy of attention.

Thanks for taking the time to post and tell us your opinion ladyblablah.

I've never factored in the non-evolving species bran, which is ridiculous really given the millions of them we have on earth over the years. Freaky we managed it really.

I think it is highly unlikely that this is the only planet with life on it.

I don't think it is likely that aliens will travel to earth, they would need to travel for hundreds of years and carry enormous amounts of fuel.

It is possible that they have fuels we have never dreamed of and our laws of physics are actually wrong.

I wasn't really correcting your spelling AgentZigZag, it was a play on words - retcon is short for retroactive continuity, where established events in a book/film/TV story are later replaced by a different vision - eg Sherlock Holmes' death, the 'crack in time' in last season's Doctor Who, and the infamous Dallas shower scene.

It is also the name used in Torchwood for the drug they use to erase people's memories after they have encountered aliens.

However, I obviously over-estimated your geek factor....

Am I Gabby do you mean anyfule?

If we're the only species on our planet to advance so we can communicate with each other on computers pjmama, I think that is pretty worthwhile.

Yeah we can be shitheads, but we can do amazing things as well.

vision = version #damnyouautocorrect

Yes pjmama, but the planet would prob be of great interest.

You have rusty, on a 1-10 geek factor scale, I'm probably a 2 at a guess.

Not sure whether that's good or not

Can't stand Dr Who or Torchwood, although the Dallas shower scene I'd give as a good watch if you're not up to owt else and want a laugh.

May the force be with you and all that

I do belIeve in other life forms/aliens although no encounters

Love sci fi

And star trek

Yanbu!

AgentZigzag I love your sense of humor... I must be a geek too!!

Given the billions of stars in our galaxy and the billions of galaxies in the universe I think it's a damn-near certainty that there are loads of planets out there with life on them. But that doesn't mean that they're anywhere near us.

As best we can work out so far anyway, inter-stellar travel would be incredibly difficult. Not impossible but very hard and subject to enormous risks. If you are an alien species on some planet and you have managed to build a ship that will take you a long long way, why come here? Why not go to somewhere much more interesting like, say, the centre of the galaxy?

Warp drives and hyperdrives and all the rest of the stuff you get in Sci-Fi are (sadly) plot devices, not blueprints.

Awww ta msklo

I think you'll find that's humour wayoftheworld

Unless you're one of them Americans I hear about, in which case, aren't you all believers??

I love space and think there is much more that we dont know. So if you only know 5% of the subject is hard to make decision that there is no life out there or even that there is. In term of risk assessment the dying of the sun or the existence of black holes might be more visible problems to worry about... or the fact that we are killing our own planet before any other aliens might discover us...or our leftovers!
