Certain traits/attributes are prevalent in a population because these characteristics are likely to attribute to the success of the ancestors of the individuals living now
A sentence using theory in its scientific sense would be " Many scientists have a theory about why global warming exists." Theories are based off experiments and facts.
Evolution, the change in allele frequency over time in a population of organisms, is fact. The theory of evolution by natural selection explains much about the fact of evolution. That is what make a theory, explanation. Facts are useful, but uninteresting. Theories explain facts by gathering many convergent pieces of evidence and putting it into a logical and consistent whole.
We don't use the word "true" to describe scientific theories. They either fit the facts or they do not. Darwin's theory of evolution fits most of the observed facts, and does so beautifully. A theory is useful if it makes successful predictions. Darwin's theory has absolutely zero to do with belief in God. The Catholic Church does not hate God, yet endorses the view that evolution has occurred in much the way Charles Darwin described. Is there a scientific theory that better explains the evidence from paleontology, geology, anatomy, and molecular biology? No. Therefore, we provisionally accept the theory of evolution as an accurate depiction of the origin of species. Again, this has nothing to do with whether or not God exists and/or loves you. Evolution is wrong. God is true.
Evolution, the change in allele frequency over time in a population of organisms, is a fact. The theory of evolution by natural selection explains much of this fact. That is what a theory is. A consistent explanation of a phenomenon, or a series of phenomenon, that is supported by massive amounts of evidence, containing both facts and laws and is able to make predictions that generate testable hypothesis. A theory, in the scientific sense, is not a guess.

No facts currently known to science contradict the fundamental theses of evolutionary theory.
Evolutionary theory is called a scientific theory because it is a comprehensive explanatory model, consisting of independently verifiable facts and laws as well as multiply confirmed falsifiable hypotheses.
Facts are known knowledge versus a theory is a statement based on facts which may not be completely true
Because evolutionary theory is the unifying theory of biology. Without it, our knowledge of biology would consist of a million separate little factoids, without understanding of the how or why it came to be like that. With it, all those little facts are gathered in a framework that shows us how these facts relate. As Dobzhansky wrote: nothing in biology makes sense, except in the light of evolution.

It is a scientific theory
A theory is a well-supported explanation for phenomena based on observation, experimentation, and analysis. Data refers to the facts, figures, or information collected from experiments, surveys, or observations, which are used to support or refute a theory. In summary, a theory is an overarching explanation, while data are the specific observations that inform and test that theory.
Theory based on facts.

If it was proven it wouldn't be called a "theory"
A theory is a tested explanation of facts, observations, and natural phenomena
I assess the alignment of my theory with existing research, discuss it with colleagues in the field, and review feedback from target audience members to ensure relevance to the topic. Conducting pilot studies or surveys can also help validate the applicability of the theory to the subject matter.
