There are plenty of objections. Polls consistently show that something like 40-50% of Americans are creationists [1]. And this doesn't mean something vague like God guided evolution, but that evolution is an outright lie promoted by scientists and possibly invented by nefarious metaphysical creatures and that in any case the Earth is only a few thousand years old, so there couldn't have been time for Evolution to happen. The fact that you probably don't know these people is more than likely a testament to how people self-segregate into like-minded groups who reinforce each others' beliefs.
All these Creationists have heard of evolution and have reasons not to believe it.
You're changing the topic. The fact that such arguments are "fully and repeatably refuted" does not dissuade people from making the arguments as much as you might think.
A (pretty smart) friend of mine tried to show me that scientists' findings about he Earth's age are wrong because he read aome article about errors in the estimation technique.
He then argued that therefore Earth is not very old and evolution didn't have time to happen.
Probably, but that's very much beside the point that a huge pile of evidence points towards theory of evolution being true.
An argument from authority (My Holy Bible says that God exists!) is quite a bit less convincing than many lines of inquiry ending up at the same place.
There is a common objection?
