My guess is that while about 30-40% of the people might suggest that the Bible is essentially correct at least about where people came from, the overwhelming majority of that population just like the overwhelming majority of the remaining 60% or so, don't have a well-formed opinion about astronomy, biology, etc. There is a large group of creationists are people who believe there was an Adam and Eve and a Noah, and have no idea about Ussher's chronology or any desire to know how old the stars are.
That does not mean that those creationists are not superstitious, but I think it is true that most people give the stuff we routinely discuss here the least bit of thought or consideration.
Under a government which imprisons any unjustly, the true place for a just man is also in prison. Thoreau: Civil Disobedience (1846)
I have never met a man so ignorant that I couldn't learn something from him. Galileo Galilei
If there is no struggle, there is no progress. Those who profess to favor freedom, and deprecate agitation, are men who want crops without plowing up the ground, they want rain without thunder and lightning. Frederick Douglass
