Yep. It's a theory, just like Euclidean geometry and Einstein's theory of relativity. What matters is the all of them are the best at modelling the physical reality when properly applied. But you don't see them trying to put disclaimers in geometry or physics books (though I think in America they don't do physics as a separate subject in high school). I suspect, though, that if they are successful in challenging evolution, they will then set their sights on physics, astronomy, etc.

Already, Grand Canyon park rangers are not allowed to state how old the canyon is according to modern geology.

The thing is, people completely ignorant of science are tryng their hand in setting science curriculum.
