The biological process which lead to intelligent life on earth was a fluke that is unlikely to have been repeated anywhere else in the universe, claims Professor Brian Cox.
The presenter and scientist blames a series of 'evolutionary bottlenecks' for the lack of extraterrestrial life on other planets, despite there being a mind-bogglingly vast number of them in the galaxy.

Humanity miraculously overcame them in a chance binding of two single cells merging somewhere in the mists of time, he said.

'There is only one advanced technological civilisation in this galaxy and there has only ever been one - and that's us. We are unique.

'It's a dizzying thought. There are billions of planets out there, surely there must have been a second genesis?

'But we must be careful because the story of life on this planet shows that the transition from single-celled life to complex life may not have been inevitable.'
He made the claims in an episode of BBC's Human Universe, adding that yet another freak occurrence - the meteor which wiped out the dinosaurs - allowed mammals and ultimately humanity to dominate the planet.

On the subject of the genesis of complex life, he added: 'We still struggle to understand how this happened. It's incredibly unusual.
'We're confident this only happened once in the oceans of the primordial earth.Life here did squeeze through.'

They need to understand exactly how complex life developed on earth and then have a good estimate of the total number of "goldilocks" planets that exist, have ever existed, and will exist in the future. Then they could say, for the sake of example, something like we're 95% sure that there's an 80% chance that we're alone in the universe(so long as earth-like evolution is the only way to create life).

Off-topic but having Putin and the new cold war will answer this question sooner. The last cold war(especially during its early phase and peak)was a golden age of scientific policy and functional and physical innovation. When there's a danger out there all sides come into agreement that science is a necessary tool for our survival, but when everything's perceived as safe and cushty then society directs itself away from science and progress and towards profit and indulgence.

Despite the endless silence observed by SETI researchers, on clear nights, whenever we turn our eyes to the stars above, it's hard not to think about what could be out there. Or, more exactly, who could be out there. It’s easy to wonder if life exists on other worlds, and if there are other beings like us somewhere, pondering the same question.

In such a vast galaxy with so many billions of stars,it seems very unlikely we'd be alone. But if they are out there, how do we find them? The Milky Way alone is so huge that alien civilizations could exist relatively nearby and we'd never even know about them. And why hasn't SETI heard anything yet?

If it wasn’t for one fascinating incident back in 1977 the whole thing would be far too depressing. On August 15th of that year, Dr. Jerry Ehman was manning the Big Ear Radio Telescope owned by Ohio State University when he spotted a most peculiar anomaly. It appeared to be a radio wave signal, distinct from the usual background noise, coming our way from outer space and showing all the telltale signs of an interstellar communication attempt.

Ehman checked and rechecked the data, then noted the word “Wow!” beside the signal on the printout. From then on it became known as the Wow! Signal.

This surprising observation led astronomer Michael Hart to conclude that spacefaring life in the Milky Way should be either galaxy-spanning or non-existent. But the exclusive presence of "non-existent spacefaring" aliens could be attributable to any number of things, including a reluctance to explore space, or owing to technological intractability. But it could also imply that aliens simply don't exist. Indeed, despite all the recent discoveries of potentially habitable exoplanets, along with the general feeling that our universe is primed for life, there are many reasons to suspect we're truly unique in the large scheme of things.

The Right Place at the Right Time

As astronomer Paul Davies has said, "If a planet is to be inhabited rather than merely habitable, two basic requirements must be met: the planet must first be suitable and then life must emerge on it at some stage."

Indeed, life is dependent on the presence of five critical elements, or metals in the parlance of astronomers: sulfur, phosphorus, oxygen, nitrogen, carbon (or SPONC for short). These heavier elements were cooked in nuclear reactions inside stars and became part of the interstellar medium only when stars reached the end of their energy-producing life. So, as time went by, the concentration of metals in the universe gradually increased.

I think most importantly the teller replaces the tale. The sound of a sentence and certain keywords replace the meaning of the sentence. What you get is a people who understand noises but don't or can't grasp ideas.

What people are saying is very much replaced by who's saying it and the style in which it is said because people don't have the basic faculties to grasp the subject. There's no better example of this than people who endlessly copy and paste, if you understand what you're pasting you should be able to re-write it in your own words, and a critically thinking audience should be able to recognise that it is the same argument written in a different way.

Obsti, i think there is a great need for a changement and evolution,, if not humanity won't progress and will stagnate, even the planet is changing at it's own pace, the problem i think is that changes were detourned for the purpose why it was created,, intillegence itself don't fix any limit, life should progress simutaneously with changes. Large part of these (changes) are creating and bringing in new ensights as to how humanity should exist with it's own creativity. Wisdom is lacking most of the time,, the proper choice and decision on what/how to adopt to derive substantial benefits out of it.

I'm sorry you don't like my style of debate.

But you have rather hijacked my thread, if you have something intelligent to add, please do.

My point would be that the stress of necessity is wisdom's one and only ally. Most people only use their brainpower when they absolutely have to, and they've not had to for longer than I've been alive.

Sure, there will always be a few who exercise their brainpower within a generation, but during decadent times you'll find that this brainpower is more aimed towards inventing new tricks and schemes on the derivatives market, or creating media and moral propaganda, and not towards curing cancer or mining Mars.

All things are relative, you can't segregate changes according to what you want and your desires,, things that are of importance on you could mean nothing to others, we don't have the same need and the same aspirations,, as well a mental faculties, you can't enduce your personal attribution/quality to the rest ,, unique progress doesn't mean anything at all,,, and i think descriminating other's efforts is a sign of negative approach.

The Victorians gave us science and factories and prosperity.

Georgian decadence gave us deregulated banks, Wall Street, globalisation, consumerism, the Great depression and both world wars.

The Greatest generation gave us factories, anti-biotics and the moon landing.

The Boomers gave us deregulated banks, Wall Street, consumerism, the Great Recession and wars of intervention.

And now I think we're overdue another leap into future akin to what the Greatest gen. or the Victorians achieved. I think we're on the cusp of massive breakthroughs in fields such as genetic engineering and artificial intelligence and these will lift our nations from the velocity of Boomer decay into the achievements of the future.

meanwhile some believe there are form states and formless states of being, that there are countless sentient beings who have been migration from life to life including formless states since beginningless time, that process since beginningless time is without possibility of end.
How then could you perceive we are the only life in this universe, as the premise of this thread suggests?

"There is only one advanced technological civilisation in this galaxy and there has only ever been one - and that's us. We are unique."

He also has failed to present any evidence whatsoever to support this claim. Noting also the Universe seems to be much larger than our current ability to see things. Currently we can only see about 14 billion light years in distance. There exists no evidence to support a contention that the range of our best radio telescopes is also the end point of the Universe. Rather instead as our telescopes improve, we will probably be able to see further. So Cox's silly presumption about who is and who isn't in the Universe lacks all scientific basis since he has no idea what the size of the Universe is, much less what is in it. Noting also there are directions in which we see nothing, simply because something else (galaxies, dust clouds, etc.) block our view.

I am a follower of Cox so my view of his reasoning differs from yours,


But thank you for your intelligent contribution to this debate.

For your elucidation.

Brian Edward Cox, OBE (born 3 March 1968), is an English physicist, and professor of particle physics in the School of Physics and Astronomy at the University of Manchester. He is best known to the public as the presenter of science programmes, especially the Wonders of... series and has been described as the natural successor for BBC's scientific programming by both David Attenborough and the late Patrick Moore. Before his academic career, Cox was a keyboard player for the bands D:Ream and Dare.
