Would you state the theory or paste a copy or furnish a link where this theory is stated and exists? Not research, the theory itself.
The method of science does not prove or disprove anything. Any variation of the term proof is not used in science. The method of science is to explain a material fact.
Maybe making points to creationists about the scientific meaning of the word "proof" is pointless.
Like a joke, I hate to explain it, but science doesn't recognize the word "proof". However unlikely, highly unlikely, it may be, it is always possible that we might find another explanation for what appears to be a "round" earth.
That simply doesn't matter.
It does when people mistakenly try to imply, or often outright claim, that evolutionary biology is somehow dependent upon, or inextricably linked to, the validity of various origin-of-life hypotheses.
They both attempt to explain the complexity of life,
No, they most certainly do not. Biogenesis does not attempt to explain the complexity of life. It attempts to explain the origin of replication, period, no matter how simple. Please try to learn something about a topic before you attempt to expound upon it.
either it's origins, or its variations, with a mechanism that has no possibility of producing those results.
Why, because you say so? Because you're unfamiliar with how evolutionary processes produce complexity and functionality?
And that mechanism is the same.
Wrong again. Evolutionary biology deals with evolutionary processes, which involve replication as a necessary ingredient. Biogenesis is pre-replication, and must obviously occur by different mechanisms. Again, please try to learn a subject before you start trying to "lecture" on it.
Chance events, and long periods of time, combine (with the help of another inadequate factor in the case of evolution...selection) to produce the most complex, intricate, and purposeful structures known.
Congratulations, you've left out some of the other necessary conditions for evolutionary processes to occur -- your description is a fallacious analogy, and utterly fails to examine, critique, analyze, or refute the actual properties of those processes. Your post is just a classic "appeal to ignorance" fallacy -- these fallacies have the general form, "because *I* can't conceive how X could take place, then it can't happen!"
Here, start your neglected education then get back to us:
To cover other anti-evolution talking points you think you might have, check out this list of common creationist claims -- each item is linked to a discussion of the weaknesses of that talking point.
- 29 Evidences for Macroevolution
- This article directly addresses the scientific evidences in favor of macroevolutionary theory and common descent. It is specifically intended for those who are scientifically minded but, for one reason or another, have come to believe that macroevolutionary theory explains little, makes few or no testable predictions, or cannot be falsified.
- Evolution and Philosophy: An Introduction
- Critics of evolutionary theory very often misunderstand the philosophical issues of the speciality known as the philosophy of science. This essay seeks to summarise some of the more important recent developments, provide a reading list, and to show that evolution is no worse off philosophically than any other science would be, and that the usual arguments against evolution from a philosophical approach fail.
- Transitional Vertebrate Fossils
- It is impossible to to debate creationists without hearing them claim that there are no transitional forms in the fossil record. This essay puts the lie to that claim by listing and briefly describing a large number of transitional fossils among the vertebrates.
- Genetic Algorithms and Evolutionary Computation
- Creationists often argue that evolutionary processes cannot create new information, or that evolution has no practical benefits. This article disproves those claims by describing the explosive growth and widespread applications of genetic algorithms, a computing technique based on principles of biological evolution.
- Introduction to Evolutionary Biology
- This essay is a must-read for anyone who wants to participate in talk.origins. It lays out the land for evolutionists and creationists alike, presenting the ideas behind and the evidence for biological evolution.
- What is Evolution?
- All too often creationists spend their time arguing with a straw-man caricature of evolution. This brief essay presents a definition of evolution that is acceptable to evolutionists.
- Evolution is a Fact and a Theory
- Biologists consider evolution to be a fact in much the same way that physicists do so for gravity. However, the mechanisms of evolution are less well understood, and it is these mechanisms that are described by several theories of evolution.

If you still have any unresolved questions or require further explanation of why you're talking nonsense, ask me and I'll cover it in more detail.
You have zero comprehension of what evolution is. Abiogenesis, by definition, cannot evolve because it cannot reproduce. While evolution totally depends on reproduction and genetic changes. These two things are in no way "the same".
"Would you state the theory or paste a copy or furnish a link where this theory is stated and exists? Not research, the theory itself."
Actually, it's a hypothesis rather than a "theory." You got me on that one. But that's semantic quibbling and is beside the main point.
Evolutionists routinely claim that the theory of evolution is separate from the origin of life. That's technically true, but if the origin of life cannot be explained by purely naturalistic means, that more or less blows away the notion that science must be premised on pure naturalism, eh?
No, science never proved the earth round or that the planets go around the sun. Science can never prove anything, the only method of science is to explain a material fact. That does not mean the earth is not round or that it does not revolve around the sun. That is observed by mathematics for things that occur as time, distance, velocity etc. Mathematics and science are two different methods for different observations.
No. All that means is we can't tell you today exactly how life began via naturalistic means. Like we couldn't tell you 100 years ago that the mechanism of inheritance was DNA.
What supernaturalists can't explain is why they believe that any supernatural thing exists at all. Besides the fact that they believe it is so.
Let me expand on that.
Natural explanations exist. Water evaporates and then condenses to form rain. Thousands of other natural processes are understood.
By contrast *no* supernatural phenomenon can be documented. None. Not fortune telling. Not ghosts. No Goddess Pele has been measured. Zeus can't bee found. Nothing, nada, zip.
So what makes you believe that any supernatural entity exists at all?
And creationists compare scientists to liberals who believe things for no reason at all ....
LOL, projection is your business.
So then, the Earth isn't round, and planets don't go around the Sun, and science never proved it, and is not capable of proving it because science can't prove anything. Is that your position?
That wasn't actually the point I was making in that post, but since you ask...
No, science does not deal in "proof". Nor does any other epistemology which deals with real-world things. "Proof" is an impossible standard in this real world. Proof is only possible in artificial realms like mathematics, where every rule and premise is exactly known because it is defined by fiat.
In the real world, however, we have to be content with lesser degrees of certainty, and less ironclad means of acquiring knowledge, because there is *always* the possibility of someday discovering something which upsets the earlier conclusions and requires their modification or replacement.
I'm not saying the Earth isn't round or that planets don't go around the Sun. There is abundant and overwhelming evidence sufficient to establish beyond reasonable doubt that it is and they do. But it is an error to mistake this for "proof" or justification for absolute, complete certainty. To use an extreme example, we might be wrong because we're actually being deceived by a Matrix-like simulation, and our real Solar system is actually something different entirely. For a more prosaic example, it might be a mistake to say that the "planets go around the Sun" because either absolute position and/or motion is an illusion and all frames of reference are equally valid (a la Einstein's relativity), or because (as recent quantum investigations may be hinting) position and motion itself is an emergent illusion due to the properties of an underlying holographic reality.
For another example, for a very long time many people would have been tempted to offer Newton's Laws of Motion as something that had been "proven". And yet, it turns out that the reality is actually much more complex, and Einstein's Relativity needs to be added to them in order to avoid serious errors under many conditions. Oops! If anyone thought they had "proof" of the validity of Newton's laws, they were quite wrong. Reality can *always* throw you a curve even after you think you have all the bases covered and have verified something to the exclusion of any error.
This is not to say that anyone who maintains that the Earth is round and/or the planets revolve around the Sun should be chastised or ridiculed -- quite the contrary, I would cheerfully ridicule anyone who tried to deny either proposition. But at the same time, I would correct anyone who maintained that either proposition had been "proven" in the sense of a mathematical proof. They have not, and they can not, be *proven*. What they have been is *established* as quite likely to be true by evidence and by testing and by having survived potential falsification tests. But this is still not *proof*. "Proof" is a different kind of standard, and indeed a different kind of method entirely.
In ordinary conversation it is acceptable to use the word "proven" as a synonym for "demonstrated" or "established beyond reasonable doubt", but in a scientific discussion, the exact nature of a proposition's state of certainty (and how that has been arrived at, and what holes that leaves open for incompleteness or applicability or error) is a big part of the whole point. Science is all *about* what has been learned, how, by what methods, how far this can be trusted, what openings are left for new surprises, what is left unexplained, etc. Cavalierly saying that something has been *proven*, when indeed it has not, is inexcusably sloppy thinking, and wildly simplistic (not to mention wrong).
While to layman it may sometimes appear that every concept in science is either held with a reckless certainty, or just a wild unsupported guess, in reality it's actually a grand mix of every degree of certainty in between (but *never* complete, we-know-we're-not-possibly-wrong certainty). Science never deals in certainties. Anyone honest with themselves will admit they can never be truly *certain* about anything (not counting the dishonest kind of "certainty" arrived at by simply refusing to consider that one might possibly be mistaken), because we're always working from incomplete knowledge and subject to human error. No one is omniscient.
But science arose from methods dealing with how to get by, and how to acquire reliable and usable knowledge, despite the lack of absolute certainty on anything. The short form is that every conclusion is provisional, and comes with mental footnotes attached concerning how complete or how poor the evidence/testing of that conclusion is, and what holes remain to be filled, etc. The flip side, however, is contrary to the layman's impression, the best progress is made *not* by only adopting the conclusions which have been established to, say, 99% confidence levels, but by using even conclusions with better than, say, 20% confidence levels, AS LONG AS one keeps in mind which conclusions are very well established and which are more tentative and one doesn't bet one's life or space probe or whatever on the more shaky ones. BUT, the point is that like an engineer who needs to complete a project with less than 100% of the information necessary, one has to go with the best conclusions one can arrive at based on the less-than-complete picture one has at the moment. ...while always striving to fill in the gaps when possible. Science is all about using the best knowledge available at any given time, even when it's not as good as you'd prefer. As it turns out from long experience, this is a far more productive method than just saying "hell, we don't know for sure" and refusing to proceed until everything is known to 99% confidence levels (or at least *appears* that way, confidence levels themselves are something that might be due to poorer information than one might presume).
So in sum, scientists get pretty picky about how certainty levels are described, because they're trained to always keep an eye on them.
And no doubt always will be. There is always "more to learn", about everything. Though on the whole, we know far more about the theory of evolution than we do about the theory of how gravity works. While there is little doubt among those who understand the issues, that evolution and gravity both "work".
Evolution is, so far, the "best" explanation (theory) for how the species came to exist, then often die off, over the eons. What anti-evolutions don't understand is that it is not sufficient to simply poke holes in evolution to "make it go away". Evolution theory must be *replaced* by something else that explains all that evidence better than evolution theory does. So far, they're not even off the starting block, and they don't even recognize how far they have to go.
See my prior post. To a scientist, it *isn't* just quibbling, it goes to the heart of science.
"No. All that means is we can't tell you today exactly how life began via naturalistic means. Like we couldn't tell you 100 years ago that the mechanism of inheritance was DNA."
You just don't get it, do you. Not only do we not know today how life began via naturalistic means, but we don't know if we will *ever* know. And not only do we not know "how" it could have happenned, but we really and truly do not know if it actually happened by purely naturalistic mechanisms. You assume that it did, but that is nothing but an assumption.
You claim that we may know someday how it happened, but that's nothing more than a guess and a hope. Get it? Hope has *nothing* to do with science. If you weren't so blinded by your assumptions, that would be obvious to you.
That is the point of the thread. Nothing more, nothing less.
That may be, but it became difficult to tell the difference after the Scopes Trial seemingly blended the two in the minds of the public. The prosecution said humans were created and did not evolve from monkeys, or at least that was the basis of the law there concerning Scopes' penalty for teaching 'evolution.'
Ever since, I suspect most folks still believe Darwin included humans as one of the groups that evolved over a period of time, rightly or wrongly. If he did, wouldn't that show that Darwin rejected the idea of 'man' popping up all at once out of the blue, so to speak? Or am I still not undertanding your point?
Thanks for your comment.
What a "crock"!
There are no variations of 1 in mathematics. 1 is 1. 1.0999 is 1.0999. 1 does not equal 1.099, et al. 1 is defined as a natural number, 1.0999 is not. And while there are no "simple proofs" that 1+1=2, it can be proved and has been. I leave that as an exercise for you.
Which crock Larry?
