In most social situations, we respect those who are recognized experts. If you were at a party and complemented your host's new marble countertop and a geologist said, "Yes, it is beautiful, but actually, it's granite," you wouldn't argue. And if you did, nobody would feel sorry for you for embarrassing yourself by contradicting the expert.
So why is it that on
one specific topic, the age of the Earth, creationists feel qualified to overrule the experts? More to the point, why do they drop the usual social norms? Why do they think it's OK to disagree with a scientist on this one topic, something they would never do on any other subject?
A high-school teacher can tell a student, "No, you are mistaken. Here is the right way to understand this problem." From a sociological perspective, the teacher is the alpha, the dominant person, and the student is submissive. There is no social
faux pas when the teacher corrects the student. It's not considered arrogant; the teacher is
supposed to be more knowledgable and is
supposed to correct the student in front of his/her peers. Nobody is embarrassed by this social dynamic.
But when a creationist violates the normal respect granted to experts by making claims that are scientifically impossible, the scientist has two choices: to become like the high-school teacher, correcting the creationist in front of everyone, or to remain silent and avoid embarrassing the host and other guests.
Creationists have
huge gaps in their knowledge when it comes to science. It's not merely that they are ignorant of scientific facts, but rather
they don't even know what science is. They often assume that science is a belief system, another set of opinions about the nature of the universe, one that's on equal footing with other belief systems.
This is completely, utterly wrong.
