I guess you mean young-earth creationists? It's easier for them to swallow than evolution because it doesn't so directly threaten their beliefs. And it doesn't need to be a total rejection; they can disregard tons proof of the age of the universe and still know enough math and engineering to make, say, microprocessors.

Of course you must have read claims like "the speed of light changes over time" and "all that light was created en-route 6000 years ago". This allows them to believe a ridiculous premise but still participate in reality and use their GPS with a clean conscience.

But I think there are many creationists who can reconcile their differences with reality by believing the seven days of creation are a metaphor or some sort of measure in "God years", so they can reject evolution like they were brainwashed to, but they have no problem believing in the speed of light and measurements of distances between stars.
