Evolution is a theory, not a fact. It has been proven neither wrong or right.
Of course not, scientific theories can never be "proven" true.
The theory of evolution is more than just a "theory." The word "theory" in normal usage means a guess or a hunch. But in science, a "theory" is a belief that has been verified by actual experimentation and/or observation.
Evolution is more than a theory; it is an established fact; the earth's structures have changed and its life forms have evolved over billions of years. Species of animals have been recently observed as continuing to evolve, both in the lab and field.
I personally believe in theistic evolution.
