Your understanding is incorrect.
Why not? You did. You said that "calling something scientifically "in error" for positing a theory which you don't agree with it just boneheaded at best, and further, is circular reasoning." Geology teaches us that the strata built up over millions of years, something this 'museum' refutes. Paleontology teaches us that the dinosaurs died out millions of years before man came into the picture, something this 'museum' refutes. Meteorology teaches us that a flood as describes in Genesis is scientifically impossible, something this 'museum' refutes. The core theories in all thouse sciences say that this museum is in error, so are they engaged in 'circular reasoning' or are they not?
Saying that this 'museum' explains science is like saying Disneyland explains history.
