All good responses, just to clarify my initial answer, i commented only on the specific example addressed, humans growing to perfection as it relates to evolution. It is not evolution in any sense, its a mere repairing of the human body.
The other examples provided are all good and show some of the inconsistencies of those who believe in pure creationism.
what phizzy says is correct regarding the wt position. they take the stance that adaptation happens within species and that there is room for some variation within “kinds”. Consider dogs and all the changes and variation through selective breeding. They would point out they are still dogs in the end. Its their way of acknowledging the obvious (selective breeding effects offspring over time) without giving into full on evolution and potentially offending their desert god.
