It's not that simple, life is on earth, but not elsewhere in the universe until proven otherwise. : Mrgreen:

Yeah yeah, it's not that simple... when we see what you say on certain subjects, we have to admit that in fact "it's not that simple"... : roll:
When we know that there are billions of galaxies, what is "simple" is to think that there is only in our solar system that there is life. A solar system which, compared to infinity, is not even the size of an atom...

When we know that there are billions of galaxies, what is "simple" is to think that there is only life in our solar system.
This is only conceivable in a vision of life of the same nature as that of our planet. For the rest, no one knows anything about it and everything is just suppositions and fantasies of all kinds. Already 'science' is incapable of knowing when this life appeared on this earth...so elsewhere!
Solar system which, compared to infinity, is not even the size of an atom...
already the fact that the "dimension" of infinity is not measurable, according to our measurement criteria, it is difficult to compare the non-comparable!

It is incorrect to say that we know nothing (which is very convenient for introducing any crazy theories) about the appearance of life; there are imprecisions of course, but there does not seem to be any impossibility in knowing when and how life appeared.
Work in physics applied to life leads us towards an understanding that allows us to arbitrate on two dualistic (and caricatured) positions that dominate the debates between believers and materialists: the thesis of life which appears by "accident" and that of life resulting from a "divine" design.

Contemporary physics now leads us towards a more enlightening path, that of maximum entropy production and self-organized criticality.
His new approaches explain why the scientific community is looking for life on other planets:life is not an accident, but a consequence of the laws of physics, subject to very strict conditions prevailing in a particular environment.
Given the vastness of the universe, it appears increasingly likely that other forms of life exist elsewhere.

How many stars are there in the Universe?
(...) We are at the end of our calculation, if there are a few hundred billion stars per galaxy and a few hundred billion galaxies, by taking the product of the two we find that there are approximately 10^23 (10 to the power of 23) stars in our observable Universe!

How many grains of sand on Earth?
Now how many grains of sand are there per m3? It depends of course on the size of the grains! In my experience, the grains are very often smaller than a millimeter, but we can still distinguish them with the naked eye. In the classification of geologists, we can call "sand" anything from 1/16th of a millimeter to 2 millimeters. I'll give you an average of 200 microns! With this average grain size, we can count about 100 billion grains of sand per cubic meter.

Finish the calculation by yourself: 10^12 m3 with 10^11 grains per cubic meter, we find 10^23 grains of sand on Earth. The same order of magnitude as the number of stars in the Universe!

It is incorrect to say that we know nothing (which is very convenient for introducing any crazy theories) about the appearance of life,
Exactly! For example, the theory of evolution, this crazy hypothesis born from an opposition to another hypothesis of some kind of creation. Which is not scientific at all, by the way.
There are some inaccuracies, of course,
This is for imprecisions, it is the package which gives an idea of ​​infinity
but there seems to be no impossibility in knowing when and how life would have appeared.
It also seems to me that if my aunt had one, she would be called my uncle, but biologically, that is not the case! Hence scientific calculations on probabilities demonstrate the opposite.
Work in physics applied to life leads us towards an understanding
Lead us to what? Towards each time even more ignorance of the subject and this without limits. Just like with grains of sand! Knowing one only demonstrates ignorance about all the others.
which allows us to arbitrate on two dualistic (and caricatured) positions which dominate the debates between believers and materialists:
On the contrary, to arbitrate, one must have the means and the skills to do so, which no individual currently possesses...or even in any future.
The thesis of life appearing by "accident" and that of life arising from a "divine" design.
Both theses cannot be proven (in the sense of current materialist sciences precisely) : Cheesy: ) and therefore the question cannot be decided otherwise. that by faith in both camps that you oppose here. Indeed, the two parties that you oppose only BELIEVE THAT since it is impossible to prove anything.
Contemporary physics is now leading us towards a more enlightening path, that of maximum entropy production and self-organized criticality.
Or an additional siding as has been the custom for centuries.
Everything lies in the way of formulating a hypothesis (another one!) which only leads to another language, but not to the substance, since there is NO PROOF (by contemporary physics) of any self-organization.
His new approaches explain why the scientific community is looking for life on other planets: life is not an accident, but a consequence of the laws of physics, subject to very strict conditions prevailing in a particular environment.
Elementary my dear Wats .. Sen no sen, for any thing to exist there must be very strict conditions called laws, which must exist BEFORE this thing, hence the question: what are and where do these laws in question come from.
Given the vastness of the universe, it appears increasingly likely that other forms of life exist elsewhere.
Except that we are not elsewhere but here and that the question arises for this here (unless we believe in some extra-terrestrialism which would have established these laws,) which brings us back to this cultural and traditional "idea" of a "god" or any other formulation, at the origin of all things.
Finish the calculation by yourself: 10^12 m3 with 10^11 grains per cubic meter, we find 10^23 grains of sand on Earth. The same order of magnitude as the number of stars in the Universe!
and that is nothing compared to the probabilities of the appearance of the slightest particle of life by chance or... accident.

Oh my! So cyclones can't appear? That'll please the insurance companies! Snowflakes too? : roll:
It would also be necessary to rename anthropogenic global warming to divine global warming! : Lol:

It is important to understand that the notion of creation, meaning a divinity organizing the world, has absolutely no place in science.
Not that scientific research compromises with an anti-religious vision, but simply because God explains nothing.
You claim that there is no self-organization? We must therefore deduce that Cyclones and other earthquakes are only the work of a demiurge...?
Diseases would also be the work of God, the seasons also, the stars...etc...etc...according to this principle we could avoid any form of explanation, the idea of ​​God would be sufficient in itself, which is not very practical for operating computers boosted by physics and chemistry! : Wink:

To say to what extent the idea of ​​God is useless in science (and has no place there), it is necessary to note the fact that there are theories which, despite their capacity to meet scientific criteria, do not advance research and end up becoming counterproductive.
We can cite the case of the theory of the (quantum) multiverse, which tells us that our universe does not have one history, but all possible histories, which explain our presence here below.
The reasoning is not, however, pulled out of a hat, but is considered by physicists to be too explanatory, even super explanatory.
Indeed, for a biologist, parallel universes are not of much use, despite the fact that quantum cosmology is inspired by very real experiences which are therefore widely used in computer science.
So what do we think of the idea of ​​a demiurge creating the world? Well, nothing at all because it does not bring any concrete elements to our knowledge of evolution.
We can always debate the existence of a creator, our existences simulated in a super-program etc., but this is more to be classified in philosophy than in science. For my part, I consider that this mainly relates to semantics...

These cyclones, and other phenomena of the same kind, obey laws like any phenomenon. What limits us is the ignorance we have of these; except for a few rare aspects that we are beginning to decode with the help of AI, itself designed by an external intervention to it. So not self-generated!
It would also be necessary to rename anthropogenic global warming to divine global warming!
Still as obsessed with a reference to some basic divine of the rejection of another origin than a blessed coincidence, which does things as well as if it were a divinity. It's a bit like those who cling to the vaccine miracle as for the other so-called divine miracles: semantic hypocrisy?
It is important to understand that the notion of creation, meaning a divinity organizing the world, has absolutely no place in science.
On the contrary, I was a creationist. scientific by my profession, before retirement.
The term creation is not a term with a unique religious function as shown by all those who use this term in a common way.
Afterwards, that some anti-religious "scientists" reject this term by philosophical opposition, it is their right; just as for other scientists who do not reject this link, Because neither this term, nor its use are the private property of anyone.
Not that scientific research compromises with an anti-religious vision, but simply because God explains nothing.
It depends on how this "god" is imagined by his opponents as well as his supporters! Indeed, to "explain" (according to what criteria?) the existence or non-existence of something - or "someone" - one must still understand its meaning and even its reason. Thus, when some evoke chance or nature and other substitutes (also abstract notions) this does not explain anything either.
You claim that there is no self-organization? We must therefore deduce that Cyclones and other earthquakes are only the work of a demiurge...?
Again this anti-religious obsession with some demiurge (you seem to have serious problems on that side!) I am not asserting anything, I am simply noting the non-existence of biological and industrial self-generation.
Diseases would also be the work of God, the seasons also, the stars...etc...etc...
Stop, once again, this anti-god obsession (whatever meaning one gives to this term) even when these facts are attributed to other semantic substitutes called nature or chance of which these phenomena would be the work. It is the snake biting its tail!
According to this principle we could avoid any form of explanation, the idea of ​​God would be sufficient in itself, which is not very practical for operating computers boosted by physics and chemistry!
no explanation can and could claim to know what is really going on, so everyone gives their opinion on what is unknown to all. As for the materials CREATED by humans, this would only confirm that the notion of creation remains the strongest in human thought since representing this reality that these computers (and all the materials that we use) are not self-generated; but that they are the result of the thought allowed by the complexity of the living whose origin is still not known "scientifically".
To say how the idea of ​​God is useless in science (and has no place there),
re obsession anti god! Great scientists find, on the contrary, that this idea of ​​a god, would explain this world better than a simple chance like the idea that a painter would explain a painting better than attributing this painting to a simple chance and other approaches that you recommend for want of anything better. All this has already been seen and reviewed and is only an additional repetition intended to self-persuade you that what cannot be "proven" materially has no existence and moreover MUST NOT exist.
It is important to note that there are theories which, despite their ability to meet scientific criteria, do not advance research and end up becoming counterproductive.
It is the nature of research to invent theories which have no more scientificity than the theory of evolution (and by the way on vaccinations or nutrition)
We can cite the case of the theory of the (quantum) multiverse, which tells us that our universe does not have one history, but all possible histories, which explain our presence here below.
The reasoning is not, however, pulled out of a hat, but is considered by physicists to be too explanatory, even super explanatory.
This kind of specialized discourse is only of interest to these bulb heads. By dint of looking at the stars, we forget that what is important is not the supposed multiverses, but daily life on THIS earth, not towards an elsewhere that ordinary humans don't give a damn about, as you notice below
Indeed, for a biologist, parallel universes are not of much use, despite the fact that quantum cosmology is inspired by very real experiences which are therefore widely used in computer science.
So what do we think of the idea of ​​a demiurge creating the world? Well, nothing at all because it does not bring any concrete elements to our knowledge of evolution.
Quite the contrary! To take the example of the sculptor, another example, his works serve as evidence of an art and skills in a particular field and therefore of time, which plays a significant role in the theory of an evolution that is scientifically unprovable biologically, in particular.
We can always debate the existence of a creator, our existences simulated in a super-program etc., but this is more to be classified in philosophy than in science. For my part, I consider that this mainly relates to semantics...
Yes, semantics plays a particular role in the field of beliefs, religious or not, which leads to diverse, even opposing, convictions, but at the same time the belief in the complete freedom of one's life also remains illusory, which is particularly true in lifestyles where biological laws are unavoidable without taking the risk of losing one's life and often in significant suffering.

It is known that all reproducible life on earth is based on a few basic building blocks. https://lecerveau.mcgill.ca/flash/d/d_0 ... her.html#2

We know a little more about the possible extraterrestrial origin
Traces of cytosine and thymine in carbonaceous meteorites: this is the incredible discovery of the team of Japanese geochemists. While the constituent elements of DNA and RNA had already been found in meteorites since the end of the 1960s, cytosine and thymine had not been detected until then. This has now been done thanks to the work of Japanese researchers who have set about meticulously analyzing three carbonaceous meteorites: the Murchison meteorite that fell in the Australian desert in 1969; the Murray meteorite (1950) and the Tagish Lake meteorite (2000). https://www.geo.fr/sciences/une-decouve ... rre-211275

Si "God is useless in science" why talk about it?

I'm not going to talk about it... since I enjoy the exciting debate between "opponents", sometimes leaning towards the arguments of some and sometimes towards those of others... just a few remarks in passing...

I would like to remind you that there are faculties of theology in many universities, and that they coexist with other faculties. There are several good reasons for this. Theology is, in my opinion, a field of research and study like any other. Any rejection of uncertified hypotheses is, moreover, a godsend (if one dares say so). : Wink: ) for the sectarian phenomenon… ignorance is even the spearhead of extremism (which by definition cannot be “religious”)

On the contrary, Descartes himself questioned the issue, seen through his statements:

If we go back to the basics like “the cause and effect relationship”… It is from this observation that Descartes would have deduced the existence of God: “If the idea of ​​God is in me, God exists; for only a perfect cause, God himself, can be at the origin of this perfect effect: the idea of ​​God…"

Whether or not it comes from Descartes' rationalism (for me there is no need to go that far...), “the idea that God would support the whole edifice of Cartesian philosophy"would be known (according to some)"not only would his idea be the first and clearest of all, but it would even precede the one we have of ourselves".

Now if we talk about life science it's a different story, since “just thinking about the conditions of the experiment would influence the results of the experiment” (some researchers tell us)… It’s intriguing and perhaps not just limited to “the living”.

In fact, science allows believers and non-believers to better understand the world around them, and curiously its research is a duty in many religions. Science provides answers to realities that religion could not explain without it. And vice versa, religion provides answers to hypotheses that science cannot understand without it as long as it does not have an answer to their explanation by something tangible and demonstrable. No, the two are not incompatible.

Proof of this is Muhammad ibn Musa al-Khwarizmi, who was a Muslim mathematician and astronomer of the 9th century, whose name was Latinized as Algoritmi, and who is considered today as the father of algebra and the founder of mathematics. As if…

And paradoxically, even though at one time witches were burned, Galileo was forced to retract his famous reply: — “and yet it turns” Religions have done a lot for the advent of science, not the other way around. : Cheesy:
So, if I have one “rational” piece of advice to give, it is to remain as tolerant as possible, for everyone to continue their research in search of knowledge, and to look for points of convergence rather than building a pyre. : Wink:
