Those scientists are wrong.
The theory of evolution is consistent with the fossil record, the genetic record, and observations spanning human history.
To clear another thing up, a theory is a specific statement of explanation of a series of observed facts. To be a valid theory that statement has to explain the facts, provide a means of testing that explanation, and containing a means of demonstrating how that the theory may shown false.
Evolution is a fully formed and mature scientific theory that's passed all the tests and it forms one of the bedrocks of modern biology.
Creationism is not a theory. God, after all, has never been proven to exist.
