"Biology" is just what biochemistry produces. There can be different "biologies", based on different biochemistries. For instance, there might be a different system for inheritance that didn't use a molecule like our DNA. It might involve different base pairs, or not use base pairs as a coding mechanism at all. Its metabolic biochemistry might not use ATP as a carrier of energy for reactions inside the cell. It could differ from our biology in countless ways. But, so long as it produced biochemical systems that replicated and passed on their characteristics to the next generation, you would get evolution....and then more complex life forms would come into being. 

As for chemical intent to become life, no, I do not suggest that. But life did arise here on Earth and there is no reason to think the conditions on the early Earth are unique in all the universe. A similar process, if not an identical one, can certainly have taken place elsewhere.

No it's not it has 12 billion years of causation to get threw before it gets to anything resembling pre biotic materials ....they are all there in your garden now ...what's not is repeatable physical enviroments at particular sequential times in its  entropy...are you suggesting a chemical intent to become prebiotic material that intends to become dynamic chemical reaction ...that looks lifelike ?

Well if it's not biolgy it's not biolgy it would just be something else...that assertion would allow you to claim any old chemical reaction life

Interesting, as you have not defined life at all, and this suggests you would artificially narrow the definition to be DNA-based.

I'm not aware that worms evolved into humans. Certainly not any extant species of worm.

No ...simply it needs to be biology or it's not life ...besides the first biology didnt use DNA or RNA  it too was a biological product   ..what biological trait would you expect a non biolgical lifeform to have to consider it life ? ..curly hair or a self replicating gene

A sun doesn't have to be the same as ours for it to be a sun. Again with the intellectually dishonest reasoning.

The Earth formed ~4.5bn years ago. The earliest signs of life we have date from about 3.5bn years ago. So it took less than a billion years, apparently. 

I don't understand what point about entropy you are trying to make. The entropy of a given chemical reaction is a fixed thing. It is the same now as it was 3.5bn years ago.

Do you know what a complex reaction is and the difference between a complex reaction and a combination of reactions ?

This was not even close to addressing the post from studiot you quoted. Please think of discussion like a conversation around a table. Studiot asked you a simple question, "Do you know what a complex reaction is and the difference between a complex reaction and a combination of reactions ?" Please answer that, because what you posted... didn't.

I'm trying to answer as fast as I can ..but I have to repeat my argument  to multiple replys ..it may not be mainstream but you know its built on stronger scientific hypothesis than your current understanding ..which I guess is why I'm experiencing hostility as well as a unusual amount of interest than some of the moderators posts  nothing in what I claim can not be backed up by scientific fact ...besides I have answered every question I have relied too ..its just not the answer they want ....🦖

No, it's not. Convergent evolution wouldn't result in identical species. But you didn't say anything about the same species emerging.

The claim that "Nothing in nature is observered (sic) to happen again or twice ...have a look yourselves! " is not the same as saying some species would emerge twice. The former is very vague* and demonstrably false, while the latter is true and unsurprising, given what we know of evolution.

 

* "nothing" covers a pretty wide range of items and phenomena. All of them, in fact. So as exchemist notes, processes repeat all the time, even if the outcomes differ.

There outcomes differ because there process can not be identical or the product that began its process...if nothing covers a wide range give an example of a dissimilar natural process producing something  the same ..it should be easy !

Er, well, I do have a degree in chemistry, in the course of which I learned a fair amount about chemical thermodynamics. So yeah I think I do have some understanding of the entropy of chemical systems, actually.

I do not assume anything "appeared from thin air". A lot of work has been done on the likely origins of the various building blocks of life. (I've read a bit of it, but it's a fast-moving field and I don't pretend to have kept up with it all.) 

But you are flailing around so wildly now that it is impossible to discern what point you are really trying to make.  

The fact is that chemical reactions are repeatable. So your original argument that nothing in nature repeats itself is patently false. 

If you want to argue that life can't have arisen anywhere else, you will need a far better argument than hogwash like that.

Nothing about this has been about "dissimilar natural process producing something the same"

You claimed that "Nothing in nature is observered (sic) to happen again or twice ...have a look yourselves! " You said nothing about processes or results. 

But you keep returning to a particular, narrowly-defined example that doesn't happen, where nobody is surprised that it doesn't happen, or rarely happens. This is known as moving the goalposts, and it's a dishonest debating tactic.

...

I remember someone I knew long ago that argued that evolution is false because a dog never gave birth to a cat. He thought that was a persuasive argument, when in fact it just showed how little he understood about evolution. I see a similar phenomenon happening here.

It's easy....why would we expect life to happen on another planet again ..when nothing else in nature is observed to ...become twice ...happen again ...appear the same from different chemicals and causations ...its not hog wash it's a diamond bullet of reality to the forehead you can not answer it despite your training....not once have you asked how I draw my conclusions but just threw the same answered questions back at me ...or another question because you couldn't dismiss my point  and if you seriously believe the possibilty of extraterrestrial life your going to need more than the hog wash of probability and possibilty ....

Still untrue, despite being repeated.

Then you have been really bad at framing this question

Is the point you want to make is that dissimilar conditions do not give identical results? Or is it dissimilar processes? Or is it that results can never be replicated exactly?

 

 

I would argue that none of these are necessarily true, or that this matters, but we need a decently-defined premise to discuss, and you haven't provided one.

You've been rebutted on all these. Is it really necessary to do that again? Ignorance of science isn't evidence, and your ignorance is rather profound. 

(and if your argument is true, I can't rebut you again, because nothing is ever observed to happen twice. Right?)

Just looked in at half time.

Lots of replies I see, but the score on my simple question (which is the key to whether or not a chemical outcome will repeat) remains stubbornly like the England - Germany score  nil - nil.

To the OP,

Andrew,

Can you clearly define what you are arguing please. The title of the thread implies a question - Why Are We alone...

You then state that nothing ever happens twice (as Swansont pointed out to you). You then move on to try and defend the argument that nothing is ever created identical to anything else. ???

Are you are arguing that there is no reason to believe abiogenisis could repeat elsewhere in the observable universe, and this is why we are alone?

Assuming this to be the case, then my answer would be that, I don't personally believe anything. I think we don't yet know enough to make a judgement on abiogenisis either way.  As far as I'm aware, we have not been successful in replicating (based our current data and understanding) abiogenisis in the lab experimentally using the basic chemicals and environmental conditions present around 4 billion years ago.

However it appears that this is what happened here on Earth, so we are confident it has happened at least once (we are good evidence), given the right conditions there is no reason to believe it may not be possible to repeat elsewhere.

How rare life emerging is, how often it may occur and how complex it may become are further arguments we can extrapolate from this original one.      

Whatever a chemical reaction is it can not be prebiotic material until  it begins the process of Abiogenesis and that Abiogenesis isn't Abiogenesis  until it has produced biology...

 Biology is life ....another natural system can not replicate the mechanics of that to get even close ..why would it   your drawing a mysterious intent on life that  you can not put your finger on ..it just seems inconceivable that we( biology) are  not that  special to not happen again...yeah we are not special but we are totally unique  as unique as our solar system ..so to consider the possibilty of extraterrestrial lifeforms seems not only anthropomorphic humanist but also  lifecist...life doesn't need to exsit we are the only species of animal that can consider exsitence ...
