Why do you fail to accept the theory of evolution? [Spirituality & Religion]

Do you understand it and still reject it? That i don't have much of a problem with.
But there are WAY too many creationists who say things like "evolution is just a theory!" and " if we evolved from apes, why are there still apes?!"

In short, their rejection comes from a place of ignorance.
I would love to clarify any issues with evolution you might have
