Ok... So you have no idea about the nature of Science.
Considering that you have been on these fora for quite a while now, I have trouble imagining that nobody explained it for you.
But, I will give you the benefit of the doubt and here is how it works:
-Bob observes a phenomenon (eg. the apple fall down, towards the ground). This direct observation is called a
fact.
-Bob wonders about the phenomenon and look for more example of it happening.
-If this phenomenon seems to be systematic (all apple and other fruits and vegetables fall toward the ground), Bob can concludes this is a universal phenomenon. This is translated by a
law, in this case, the law of universal grocery.
-If Bob has an explanation for these phenomena and the law, this explanation becomes a
hypothesis
-This hypothesis, in turn allows to make predictions. These predictions are compared to what happen in reality, more observations, meaning more facts: (if I drop a pea and a watermelon in a vacuum, they should accelerate at the same rate) this allows to check the hypothesis.
-Of course, if these tests disprove the hypothesis, (bananas go up! -insert homoerotic joke here, if you must-), it is then mercilessly discarded or undergo modifications.
Similarly, if one observation is made that contradict the law, the observation is finned according to the severity of the violati... Actually, no, the Law is just discarded as 'not being a natural law finally, my bad, carry on'.
-If, after robust testing, the hypothesis survives, it can be taken seriously. At this point, it is referred to as a
theory (the theory of universal grocery).
-Please note that
a law is not 'better' than a theory.
In fact, as a theory as some explicative power to it than a law lacks, it could be considered better. In fact, for many theory, you could write down a corresponding law (for example describing that species change through time would be considered the 'Law of Evolution'), but that'd be rather useless.
-Obviously, a theory can and will still be tested and there is always a chance that it will end up being proven wrong. But, of course, the more testing a theory has been through, the more thorough the testing, the less likely it is that something will come up that was previously overlooked.
So, a theory, is
never,
ever proven and it would be an especially mistaken statement to assume that a 'proven theory' become a law.
The best we can say is that a theory has been very thoroughly tested and is
unlikely to be disproved at that point.
The Theory of Evolution is like that.
As the sticker says: 'This book contains material about the Theory of Evolution.
Evolution is just a theory, which means the highest level of confidence a scientific explanation can reach, and has been as thoroughly tested than any other such theory in the history of Science. As such it should be approached with an open mind, considered critically and enthusiastically adopted as a beautiful achievement of the human mind!'
So, there you go. Hope that clears up your little misunderstanding...
