Response: Amazing. You post the definition of "theory", read it, and still can't understand the meaning. Nowhere, even in the definition which you've provided, does it say that a "theory" is a fact. The word "fact" is not even there.
This alone holds as evidence of how a person is programmed. You've been programmed so severely that you can't even comprehend what you've read. How unfortunate it is.
Ok, someone is confusing a scientific theory with the everyday use of the word. When scientists use the word theory, it has a different meaning to normal everyday use. In science, a theory is not a guess, not a hunch. It's a well-substantiated, well-supported, well-documented explanation for our observations.Some people think that in science, you have a theory, and once it's proven, it becomes a law. That's not how it works.A theory never becomes a law. In fact, if there was a hierarchy of science, theories would be higher than laws. There is nothing higher, or better, than a theory.These explanations are called theories, and will always be theories. They can't be changed into laws, because laws are different things. Laws describe, and theories explain.Just because it's called a theory of gravity, doesn't mean that it's just a guess.The Theory of Evolution by Natural Selection is our best explanation for the fact of evolution. This is what a scientific theory is.
