It's pretty easy, and it's been done to death. Most of their arguments are strawmen, in that they make a false or misunderstood claim to attack, instead of a more difficult, legitimate claim. For instance, that the creation of proteins is astronomically improbable, therefore it couldn't have happened. Since they mistakenly think the universe is only a few thousand years old, they can't accept that evolution had millions of years to miss before it finally hit.
Many of the arguments are nitpicking Darwin, as if the theory began and ended with him. They ignore what every scientist knows, that theories are dynamic, changing as new evidence shapes them into better and more accurate predictions.
And they keep repeating arguments that have been refuted, which is seriously dishonest from an intellectual perspective. I still hear "If we descended from monkeys, why do we still have monkeys?" being spread to ignorant audiences. They study evolution only enough to cherry-pick the parts many don't understand, and then ask questions they don't want answers to. If they really studied evolution sincerely, with an open mind, they would come to the obvious conclusion that there's no other way it could work. Evolution is a fact, and the Theory of Evolution describes how it works, with observational accuracy backed up by more evidence than almost any other theory.
