The problem that we Creationists will always have with the "belief system of evolution" is that you believe life evolved without a Creator, and we do not. You say it's proven science, and we most emphatically say it's not! I believe in the science that studies the disease of polio, and then develops a cure, saving countless millions from this dredful disease.
Biologists will tell you that it is evolutionary theory that underpins all biology, and fortunately, it effects their way of thinking. In order to develop both the first injected and the first oral polio vaccinations, it was necessary to use organisms related to those on whom the vaccination would be used in ways that would be difficult or impossible ethically to involve humans. But, for creationists, only humans are related to humans.
Fortunately, the biologists were evolutionists, so they knew where to look. So, John, when you thank those biologists for their science that you say you believe in, you could also thank our simian cousins for the role that they played. And you could reflect that countless lives were saved not only because we have close relatives in the wild, but because modern biologists, thanks to the work of people like Darwin, are well aware of that fact.
Now, you try and think up some practical value in teaching so called "creationist science" in schools.
There are not only the "principles of world view", as this thread's title would have it, but there are the vastly different practicalities of different world views.
