I fail to see a relevant comparison...and yes, if you call up the National Academy of Science they will tell you that the theory of evolution is so widely accepted by scientists all over the world that it is indeed considered scientific fact.
It is an incredibly well studied and documented phenomena...as is world war 2 for that matter. Anything that includes a "higher power" of any sort has gone beyond even the ability to accurately document its effects on the natural world. Therefore, by right of the argument that evolution cannot be proven because it cannot be reproduced, ID failes because no one even know what to reproduce in the first place as it is an intangible. One way or the other, ID and creationism, while popular, cannot even be condidered viable SCIENTIFIC theories to be included in SCIENCE class.
