theory In science, an explanation for some phenomenon which is based on observation, experimentation, and reasoning. In popular use, a theory is often assumed to imply mere speculation, but in science, something is not called a theory until it has been confirmed over the course of many independent experiments. Theories are more certain than hypotheses, but less certain than laws. A tentative theory about the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena; "a scientific hypothesis that survives experimental testing becomes a scientific theory"; "he proposed a fresh theory of alkalis that later was accepted in chemical practices". a concept that is not yet verified but that if true would explain certain facts or phenomena; This says a mouthful but I suppose leaves a bitter taste in your mouth.

That definition is inadequate and even wrong in a place (theories are not more or less "certain" than laws; theories and laws are different kinds of statements period), but even that definition does not mesh with your dishonest usage of the word "theory".

A theory in science is a general explanation behind observed phenomenon based upon observation, experimentation and reasoning. That much is correct. Which means that evolution is an explanation based upon observation, experimentation and reasoning. Except that you've tried to imply that evolution is nothing more than speculation. That's why you're being fundamentally dishonest.

As for the comparison with laws; laws in science are general statements about what has been observed. They do not explain anything, they simply act as a predictor for future observations. Laws are no more or less certain than theories; a law could be found to be false just as easily as a theory. In fact, Newton's Law of Universal gravitation is actually false. It works "well enough" under many conditions, but it breaks down at a certain point and becomes inadequate for making predictions on certain scales. Moreover, Newton's Law does not explain what causes gravitational force. The explanation lies in the theory of gravity, also known as the theory of general relativity.
