I wouldn't mind hearing your take on it (definition of direct evidence), sure. Do you accept that Mt. Vesuvius erupted in 79 A.D.? If yes, what direct evidence do you think exists for that event?
There is none.
Do you know that mountains erupt? Yes or no.
No, mountains do not erupt. Volcanoes do.
Say you did not know, How would you find out?
Well, in the case of volcanic eruptions, were I a volcanologist, I would know what evidence volcanic eruptions leave behind. And were I digging around and came across what looked like the same kind of evidence I know eruptions produce but buried deep in the ground, I might make an hypothesis that what I was seeing is the result of a volcanic eruption in he past (because of the law of superposition).
You?
Let us say that you never saw mountains erupt, and it takes millions of years.
Nobody has ever seen a mountain erupt, but we do experience volcanic eruptions and they do not take millions of years.
I thought you were going to define "direct evidence" for me?
And from this diversion, I am assuming that you do not think Vesuvius erupted in 19 A.D.?
Would you mind demonstrating that you would not have to interpret, and make suppositions, in order to draw conclusions.
Are you saying that the conclusions of volcanologists and geologists regarding the eruption of Vesuvius in 79 A.D. was based on 'suppositions'?
Do tell me which ones. You have used this term before, but I want you to tell me what suppositions went into determining that Vesuvius erupted in 79 A. D.
Can you say that your conclusions are 100% correct?
I could say that conclusions regarding the 79 A.D. eruption of Vesuvius is quite close to 100% correct based on the evidence.
Here is one.
You never saw a plane in your life.
Out of the blue, you saw one.
How would you go about figuring out how it came to be?
Well, I would look at it and I would notice that it shows evidence of manufacture - screws, welding joints, rivets, etc. I would look inside and note that it appears to have been made for humans, and since I know that humans weld and screw and rivet metal, I would conclude that humans made it.
Since you are desperately avoiding providing a simple answer to my question, allow me to also insert a digression -
Say you looked in a microscope for the first time and saw some cells. How would you determine what they were and where they came form?
Your response will tell us whether or not you are serious in this 'debate.'
What?
If there is evidence there is no need for supposition. Do you not get that?
No I don't. Explain it to me please.
To start, I don't think you actually know what
supposition means:
A belief held without proof or certain knowledge; an assumption or hypothesis.
‘they were working on the supposition that his death was murder’
If you had supposed that his death was murder (using the dictionary example), then found evidence that the dead person had been shot 3 times in the back and strangled, it is no longer supposition, is it?
Until it loses support with further research that turns that support on its head. Then what? We continue our research. That's science, right?
Unless is a better word choice. Yes, science keeps chugging along while religion stays right in the 3 millenium B.C. Not all hypotheses are overturned. The major theories we have in science today (relativity, evolution, cell theory, etc.), we have
because the broad sweep of their evidence and applications have NOT been falsified.
Keep in mind that falsifiable does not mean falsified - funny how little so many creationists understand these things. I once had a creationist bring up Popper and the falsification criterion, and this creationist declared that evolution was false because it had not been falsified. He thought that you had to falsify something in order to accept it.
Funny.
Science knowledge is subject to change in the light of new evidence or new interpretation of existing evidence.
Yes, but see above.
I note that your belief system refuses to be altered by new evidence or interpretations.
Which is better? The system that 'admits' it is imperfect and is willing to adjust as needed, or the system that denies contrary findings no matter what?
May I ask, are you a scientist? Why are you asking me this?
Yes, I am, though no longer a very active one (research-wise). I asked because YOU brought it up.
A supported (correct) hypothesis is in and of itself not 'an argument.' It may be used AS evidence in an argument for something else, but a 'proven' hypothesis is just that.
If a hypothesis is correct, why does it need to change,
It doesn't
need to. It might
have to if new evidence is found that better explains the phenomenon.
One example from a non-contested science - Gravity. Newton's theory of gravity broke down in the case of certain planetary orbits, which were later better explained by relativity.
Does this mean that we are now free to float about if we wish because 'the theory of gravity was falsified'? No - Newton's gravity (if I can call it that) still works for most applications, and when it doesn't, we have relativity/quantum mechanics (physicists please correct my loose terminology as needed).
Back to hypotheses - you do understand that an hypothesis is not a 'theory' in today's scientific usage of the term, right? Because that is what your line of questioning is starting to hint at. And if so, then
I think your line of questioning belies the naivete in your understanding of science.
and would it being used as evidence, not mean that, ideas are being use as evidence - even though these ideas are really only being supported by other ideas?
You keep leaving out the evidence.
Thank you for honestly putting proven in inverted commas.
I also put 'an argument' in
'inverted commas.'
So no argument, then.
The point I made was that you were taking the content of a press release, in which the author of the press release used the sort of sensationalist language that a layman would use, as 'evidence' that pelvic bones in whales have a function and thus are not vestigial.
The issue is that why should whales have pelvic bones at all if they were 'created' to live in the oceans? Evolution explains why they have these bones. Creationism makes farcical assertions.
Did the whale need these bones on land, or in the ocean?
When the whale's ancestors were terrestrial, they used them to ambulate.
I thought it was the ocean, therefore, I don't see how creation is ruled out.
Creation can never be ruled out
emotionally because one can always posit 'the creator's whim' for an absurdity like the platypus (according to creationist lawyer Phil Johnson) or that 'the creator did it, so it is all good' as with these vestigial pelvi.
But
scientifically, there is simply no reason to posit a creator in the first place.
Dolphins have them also, don't they?
I presume so, but I don;t know for certain. I know that a percentage of Minke whales are born with not only rudimentary pelvic bones but femurs, as well. And I know that the embryos of dolphins exhibit hind limb buds early in development, which are then resorbed. And I know that as mammals, whales and in fact all other vertebrates exhibit shockingly similar early developmental patters in things like their vertebral columns, circulatory system, basic brain structure, etc. All of which adds weight to the evolutionary explanation.
Sorry about that. I plan on doing things a bit differently, but there were two links, and I don't think you commented on the second.
And you did not comment on any of mine. In case you have not read many of my posts, be aware that I have been involved in this 'debate' for almost 30 years. I have a dozen creationist books on the shelf behind me, along with several volumes of creation 'science' journals. I have seen 2 professional creationist lectures/debates. I have in my archives hundreds of creationist essays, web articles, etc. And I have also published original research in the field of evolutionary biology and have taught related classes at the university level for 20 years. I have exchanged emails with many 'professional' creationists over the years, to INCLUDE Jeff Tomkins (who I had to reach through an intermediary - I asked when he planned to assess the DNA relationships within the created kinds - he did not answer but told me he was right about chimps... whatever..). Point is - there is very little you can present to me from creationists that I have not already encountered and if it is in my field, debunked.
I see evidence, as information gathered primarily through the senses, which can lead one to believe something.
So while you may think, or believe that you have evidence for evolution, by examining that information, another person may look at that same information and say that evidence does not support evolution - to them it supports something entirely different.
And literally every time I have been told this and then given examples, the only interpretation the creationist has is that they believe it shows God did it. Never an actual explanation of any kind - but far far more frequently, all I get is the sort of nonsense Tomkins puts out.
So why do you think you are right in calling the person a liar? Would the person not be right to return that "compliment"?
Were I lying, yes.
That person merely dismisses the evidence, claiming it to be 'guesses' and the like, but the person is totally incompetent - by her own admission - to even understand the evidence. But that does not stop her from making the same lie over and over about there being no evidence of revolution.
Say I claimed there to be no evidence for the global flood. That I was well versed in all the claimed evidence for a global flood, and that I know that it is all guesses and suppositions and nonsense, and you presented some material that you felt supported the claim that the flood really happened. And rather than delve into the material and try to assess it, I instead asked you to dumb-it-down for me, so I could understand what you had presented. And then I simply ignored it and wrote again later that there is no evidence for the flood?
And that this type of exchange happened repeatedly, over the course of years. Would you consider me an honest person?
I should hope not.
Yes, thank you. I was asking how these parasites that depends on a host, survived.
I cannot speak for all parasites, as that is not my field, but I believe that there is some genetic evidence in tape worms that they experienced mutations that basically caused their digestive systems to become non-functional. They may have started out as just crawling inside creatures now and then for food, but as their digestive systems became non-functional, had to simply stay in their host. Again, not my area, so I don't know the details.
