Different fields of study use strong in different manners, so I'll clarify what I mean by strong. A statement is strong if there are less cases in which it may be true. Essentially, it's the same as when you say "Well sir, that's a pretty strong statement". It entails boldness. The fact that creationism rests on so many assumptions, yet hasn't been straight out proven false (from what I've seen) only serves to emphasize the opposing view.
Creationism isnt a "strong theory", it is a poorly drafted theory with MANY logical fallacies, and cant even be called a good "theory". At best it is a poorly drafted hypothesis.
Again, I'm not commenting on how good creationism is or is not. I'm simply pointing out that neither creationism nor evolution have met outright contradictions (That I have seen at least).
You are also misrepresenting the word theory when you attempt to attack evolution. It isnt just "the strongest will survive". That is a large part of it, as it specifies natural selection, which is the cause of a majority of genetic filtering among species, but it isnt quite that simple.
I'm not misrepresenting the word at all. It's true that the term is loosely used as simply an explanatory statement (And in this respect, evolution meets the criteria), but a
good theory not only has explanatory value, but predictive value as well. Evolution and Creationism are flawed in this sense. Although both may give ad hoc explanations for why things are the way they are, neither tells us how to predict what we will see the in the future. Good theories, on the other hand, do give us predictions. For instance, the science that lies behind cars allows us to make blueprints about how we expect a car to function *before* it is built. That does not mean there are errors upon creation, but typically, those errors arise due to the manufacturing rather than due to the scientific tools (i.e. calculating velocity and energy) that lie behind the construction. The same occurs with weather when we use science to make predictions. Of course, once again, flaws occur, but they do so because of inaccurate measurements rather than because of the theories behind environmental science.
I'm well aware of natural selection, but essentially, isn't the core of that suggesting those with adequate properties to survive are the ones that survive and the rest perish (Before offspr, thus, leaving only a specific group of genes left in the pool? Scratch that; I'll just post a working definition so as to not arouse anger and rage over this:
* Organisms produce more offspring than can survive and reproduce.
* Those that do survive tend to be better adapted to local environments.
* Most adaptations are genetic, so they can be passed from parent to offspring.

Yes, I realize you can get more detailed on the matter. If you have more to add, then do so, because quite frankly, I've yet to run into a definition that escapes the problem. What does natural selection predict about the future? It essentially tells me that creatures in the future will be who they are because their genes were not eliminated (i.e. because they were "strong"). That's nice, but what can I specifically say about the characteristics of these creatures? In other words, can will I have so much knowledge about them that I can envision exactly what their traits and functions will be like in the same way I can construct an missile and have a damn good idea of how it will work?
Another important point about theories is that you should be able to disprove them. So tell me, how would I disprove evolution? I can't say "Oh well this gene isn't here, so it's wrong" because that would signal that the gene was simply not fit or not strong enough to survive. No matter what the outcome is, evolution can cover its ass much like how Freudian psychology did in many cases. No matter what the final composition or outcome is, evolution simply tells you that what is left is because you had traits that could survive until now.
Actually, there is a very compelling way to disprove the theory which would be to find a creature with no ancestral roots. That would require that we first know every creature in existence and then are able to look back in history and trace that creature's origins. Anyone looking into this problem will immediately note the chaos that ensues like with most other theories (Which is not necessarily bad at all). So on that note, I'll concede that evolution is explanatory in the sense that it predicts all creatures of the future will have an ancestor (note that I wrote most of this post before reconsidering the issue). The problem I see with this is that it misses the entire question evolution was intended to solve (Or at least what I speculate it was intended to solve), but more on that later.
You cant even compare creationism as a "theory" to evolution as a "theory", they arent even in the same league.
Whether two things are of the same league depends on your threshold of perception for defining leagues. Until you or someone else brings forth the predictive values of one or the other (And I have seen very close attempts with evolution), I will continue to consider both of them garbage.
This brings me to my next point which is that a
good theory will probably not emerge until all other sciences complete. To see what I mean, you must ask yourself why these theories are emerging in the first place. What question is evolution trying to answer? I've actually seen different answers to this question, so I'll let you respond (in PMs) and one that I've seen. It attempts to answer "Why are do creatures have the features they have?". The prediction question would be "What feature will creatures have in the future and why?". If we accept these as our questions, then evolution offers is an incomplete theory for the latter because it says that the only defining characteristic of a creature is that it will have an ancestor. It works nicely as an ad hoc explanation for the former. Why? It's because we have facts about history and can make conjectures based on these facts. The explanatory component, however, requires information on the future (i.e. predictions). Not only that, but the magnitude of the theory, because it encompasses all creatures, means we need not just information on a specific object or the environment, but also information from the social sciences in order to calculate interactions between individuals. In other words, until we make vast progress in social sciences, evolution will have relatively little foresight value. Environmental science's predictions struggle for the same reason, but it's less encompassing and has more patterns that allow it to make fairly good predictions.
Maybe Im misunderstanding you or something, but were you really trying to infer that evolution was just as rediculous as creationism? I hope not.
I'm saying they both fall far behind by
my standards. I'm not religious, if that's what you're presupposing when you read my responses. At the same time, grasping at the fundamentals of a statement and piecing out its components is not bad either. Other than that, I will leave responses to PMs as well because these type of threads and debates take too much time and threads have time horizons as far as salience is concerned.
I can clarify a part of what he said for you. The "ratio level of measurement" thing comes from a point he made in another thread about temperature scales originally being poor "theories" since without a minimum temperature of absolute zero, temperatures can't be compared to one another proportionally. For instance a temp in Celsius can't be said to be x times hotter/colder than another temp in farenheit.
Clarification: It's that the scales, though consistent with
themselves, don't give a strict definition (or in some cases "good") of what it is trying to measure. The intervals chosen are arbitrary. I will admit that it's difficult to point out in the core sciences, but it's a fairly common one in the social sciences, so I'll give you an example using that. Lets say I want to measure how good a worker is. I assign four criteria which the individual must meet and for each one he hits, he is given a point. If a worker (a) hits all four criteria and worker (g) hits one, does that mean worker (a) is four times as good as worker (g)? If your definition of good relies strictly on those criteria, then it does. However, these were just arbitrarily chosen criteria. We cannot apply this so that it functions with everyone's definition of good. It works at the interval level because each criteria and point granted is weighed evenly, but it doesn't hit at the problem at hand. Now lets apply this to temperature since you brought up my example. When we talk about temperature, what are we measuring? It's agreed upon that we're talking about the average kinetic energy. Now lets look at our scales: Kelvin, Celsius, and Fahrenheit. Which one of these truly measures that? Kelvin. I use the zero-reference point argument because it's easy to understand that at 0 Degrees Kelvin, we're insinuating 0 Average Kinetic Energy. On the other hand, can we say the same about Celsius and Fahrenheit? Not quite. You must then ask yourself, "what exactly does it mean to say you have 50 degrees C/F?". Compare that to what it means to have 50 degrees K. Therein lies the answer to what I've been trying to communicate.
Apparently without that "ratio level measurement" they were meaningless as units of scale
It's not that the measurement is meaningless - it's that the object of measurement becomes skewed. However, until we reach that point, we typically make assumptions (because we are ignorant) and work with what we have until that point is reached.
