answer: Because they are afraid the goofy museum happens to be right (or at least conforms to the evidence better than darwinism).
Frightened is not the correct concept. The concept is that science must not be hijacked and changed to suit beliefs.
I am not afraid. You shouldn’t be afraid either. Scientists do not hold onto falsehood. Scientists are willing, in fact eager, to prove theories false. If it’s false we want to know that as soon as possible.
That’s why it’s never good enough to do science once. It has to be replicated by many other people at different locations over a long time before it is accepted as true.
Science never tries to defend it’s theories. It tries to find the truth regardless of where truth leads. Science defends truth, it doesn’t fear truth.
Science is dispassionate.
