Of course not. One need not be an atheist to be willing to follow data whereever it leads.
If the evidence were there, it should be taught as such.
But it isn't.
This is a two-edged sword. If the evidence shows, for example, that the Flood was not worldwide (this was *known* in the 1830's, decades before Darwin's "Origin"), should any thing else be taught as science?
It is a *fact* that the overwhelming majority of biologists, etc, are evos. It does no-one any good for a teacher to lie about widespread doubts in the biology camp.
Until creationism/id is able to make detailed predictions, and sticks its neck out by possibly being falsifed by new evidence, it is not a theory - it is merely armchair speculation, a hypothesis
