Like how Christians try to slaughter the law of evolution by saying that it is a theory when we have more evidence that evolution is correct then they do that the bible is not a 2,000 year old bunch of bullstuff?
Evolution is a theory. It's a theory because we cannot see it in action. For instance, there is a THEORY of Relativity, and a THEORY of Tectonic [plates], but we both know those are very true. The scientific definition of theory is something that has substantial evidence for it but simply cannot be proven. We know Evolution to be true, but cannot see it in action, simply because it takes millions and millions of years to take place.
Our defintion for "Theory" is hunch. I have a theory that Colten is Jewish and I have a theory that Ladios not good computers. However, neither of those, in any way, or scientific theories.
