Is that not enough for you?
Read my lips. Theory of evolution. Not fact of evolution. Anybody can edit Wikipedia to say whatever he wants.
You seem to be stuck on the misunderstanding of the word theory...
theory does not mean hypothesishttps://en.wikipedia.org/wiki/TheoryA theory is not the same as a hypothesis. A theory provides an explanatory framework for some observation, and from the assumptions of the explanation follows a number of possible hypotheses that can be tested in order to provide support for, or challenge, the theory.
A theory can be normative (or prescriptive), meaning a postulation about what ought to be. It provides "goals, norms, and standards". A theory can be a body of knowledge, which may or may not be associated with particular explanatory models. To theorize is to develop this body of knowledge
The formal scientific definition of "theory" is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well established that no new evidence is likely to alter them substantially. For example, no new evidence will demonstrate that the Earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the Earth is not divided into solid plates that have moved over geological timescales (the theory of plate tectonics)...One of the most useful properties of scientific theories is that they can be used to make predictions about natural events or phenomena that have not yet been observed
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. The theory of biological evolution is more than "just a theory." It is as factual an explanation of the universe as the atomic theory of matter or the germ theory of disease. Our understanding of gravity is still a work in progress. But the phenomenon of gravity, like evolution, is an accepted fact

theory
[thee-uh-ree, theer-ee]
noun, plural theories.
1. a coherent group of tested general propositions, commonly regarded as correct, that can be used as principles of explanation and prediction for a class of phenomena:
Einstein's theory of relativity.
Synonyms: principle, law, doctrine.
2. a proposed explanation whose status is still conjectural and subject to experimentation, in contrast to well-established propositions that are regarded as reporting matters of actual fact.
Synonyms: idea, notion hypothesis, postulate.
Antonyms: practice, verification, corroboration, substantiation.
3. Mathematics. a body of principles, theorems, or the like, belonging to one subject:
number theory.
4. the branch of a science or art that deals with its principles or methods, as distinguished from its practice:
music theory.
5. a particular conception or view of something to be done or of the method of doing it; a system of rules or principles:
conflicting theories of how children best learn to read.
6. contemplation or speculation:

8. in theory, ideally; hypothetically:
In theory, mapping the human genome may lead to thousands of cures.
All the definitions, even the ones you posted, have at least a factor of uncertainty in them.
