Evolution has abundant evidence. More than enough to establish it as fact, that species do in fact evolve;
''So when scientists talk about the theory of evolution—or the atomic theory or the theory of relativity, for that matter—they are not expressing reservations about its truth.
In addition to the
theory of evolution, meaning the idea of descent with modification, one may also speak of the
fact of evolution. The NAS defines a fact as “an observation that has been repeatedly confirmed and for all practical purposes is accepted as ‘true.’”
The fossil record and abundant other evidence testify that organisms have evolved through time. Although no one observed those transformations, the indirect evidence is clear, unambiguous and compelling.''
