Semester 2-Blog #1-Why is evolution a theory and not a law?

Why is evolution a theory and not a law?
To begin with, what are the definitions of evolution, theory, and law?
Well, evolution, or change over time, is the process by which modern organisms change over time.
However, a scientific theory is a well-supported testable explanation of phenomena that have occured in the natural world. Additionally, evolutionary theory is a collection of scientific facts,observations, and hypotheses.
Lastly, law is a scientific generaliztion based on experimental observations of physical behavior.

As stated, (evolution) organisms can change overtime; therefore, a theory can only be proven/supported when things has happened in the natural world. For example, Darwin had made numerous observations and gathered evidence that later led him to propose revolutionary hypothesis about the way life changes over time. Evolution is based on the changes of time which is also what a theory is based on to be proven correct.
A law has no contribution with evoultion whatsoever...it even states it in the biology book-the chapter of evoultion.
