The problem here is that many of you are attempting to spin the definition of a scientific theory. In order for something to be called a theory...it must be observable, testable, and predictable....i.e. Gravity is a theory because its effects meet this criteria.
Testable - Drop something
Observable - That something falls
Predictable - What goes up, must come down.
In practice, Evolution is neither fact, nor theory because it is "Assumed" to be correct prior to any research being conducted.....ie.."Evolution is an irrefutable scientific fact..."Now lets go find some evidence to prove it".
Contrary to the assertions of main stream evolutionists (who also just happen to be atheists by the way), evolution is not testable, nor can it make any predictions. Sure one can assert that evolution is observable through fossil records; but if the records were as clear and unambiguous as many claim then there wouldnt be any disagreement among scientists.
